* ocfs2: allocation reservationsMark Fasheh2010-05-069-11/+1091
| | | | | | | | | | | | | | | | | | | | This patch improves Ocfs2 allocation policy by allowing an inode to reserve a portion of the local alloc bitmap for itself. The reserved portion (allocation window) is advisory in that other allocation windows might steal it if the local alloc bitmap becomes full. Otherwise, the reservations are honored and guaranteed to be free. When the local alloc window is moved to a different portion of the bitmap, existing reservations are discarded. Reservation windows are represented internally by a red-black tree. Within that tree, each node represents the reservation window of one inode. An LRU of active reservations is also maintained. When new data is written, we allocate it from the inodes window. When all bits in a window are exhausted, we allocate a new one as close to the previous one as possible. Should we not find free space, an existing reservation is pulled off the LRU and cannibalized. Signed-off-by: Mark Fasheh <mfasheh@suse.com>
* ocfs2: Make ocfs2_journal_dirty() void.Joel Becker2010-05-0614-431/+102
| | | | | | | | | | | | | | | | | | | jbd[2]_journal_dirty_metadata() only returns 0. It's been returning 0 since before the kernel moved to git. There is no point in checking this error. ocfs2_journal_dirty() has been faithfully returning the status since the beginning. All over ocfs2, we have blocks of code checking this can't fail status. In the past few years, we've tried to avoid adding these checks, because they are pointless. But anyone who looks at our code assumes they are needed. Finally, ocfs2_journal_dirty() is made a void function. All error checking is removed from other files. We'll BUG_ON() the status of jbd2_journal_dirty_metadata() just in case they change it someday. They won't. Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Clear undo bits when local alloc is freedMark Fasheh2010-03-244-46/+95
| | | | | | | | | | | | | | When the local alloc file changes windows, unused bits are freed back to the global bitmap. By defnition, those bits can not be in use by any file. Also, the local alloc will never have been able to allocate those bits if they were part of a previous truncate. Therefore it makes sense that we should clear unused local alloc bits in the undo buffer so that they can be used immediatly.

* ocfs2: Fix the update of name_offset when removing xattrsTao Ma2010-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When replacing a xattr's value, in some case we wipe its name/value first and then re-add it. The wipe is done by ocfs2_xa_block_wipe_namevalue() when the xattr is in the inode or block. We currently adjust name_offset for all the entries which have (offset < name_offset). This does not adjust the entrie we're replacing. Since we are replacing the entry, we don't adjust the total entry count. When we calculate a new namevalue location, we trust the entries now-wrong offset in ocfs2_xa_get_free_start(). The solution is to also adjust the name_offset for the replaced entry, allowing ocfs2_xa_get_free_start() to calculate the new namevalue location correctly. The following script can trigger a kernel panic easily. echo 'y'|mkfs.ocfs2 --fs-features=local,xattr -b 4K $DEVICE mount -t ocfs2 $DEVICE $MNT_DIR FILE=$MNT_DIR/$RANDOM for((i=0;i<76;i++)) do string_76="a$string_76" done string_78="aa$string_76" string_82="aaaa$string_78" touch $FILE setfattr -n 'user.test1234567890' -v $string_76 $FILE setfattr -n 'user.test1234567890' -v $string_78 $FILE setfattr -n 'user.test1234567890' -v $string_82 $FILE Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Always try for maximum bits with new local alloc windowsMark Fasheh2010-03-181-2/+2
| | | | | | | | | | | | | | | What we were doing before was to ask for the current window size as the maximum allocation. This had the effect of limiting the amount of allocation we could get for the local alloc during times when the window size was shrunk due to fragmentation. In some cases, that could actually *increase* fragmentation by artificially limiting the number of bits we can accept. So while we still want to ask for a minimum number of bits equal to window size, there is no reason why we should limit the number of bits the local alloc should accept. Hence always allow the maximum number of local alloc bits. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: set i_mode on disk during acl operationsMark Fasheh2010-03-171-5/+72
| | | | | | | | | | | | ocfs2_set_acl() and ocfs2_init_acl() were setting i_mode on the in-memory inode, but never setting it on the disk copy. Thus, acls were some times not getting propagated between nodes. This patch fixes the issue by adding a helper function ocfs2_acl_set_mode() which does this the right way. ocfs2_set_acl() and ocfs2_init_acl() are then updated to call ocfs2_acl_set_mode().

| | | | | | | | | | | | | | | | | In ocfs2_validate_gd_parent, we check bg_chain against the cl_next_free_rec of the dinode. Actually in resize, we have the chance of bg_chain == cl_next_free_rec. So add some additional condition check for it. I also rename paramter "clean_error" to "resize", since the old one is not clearly enough to indicate that we should only meet with this case in resize. btw, the correpsonding bug is http://oss.oracle.com/bugzilla/show_bug.cgi?id=1230.

The problem is similar to the one reported for NFS by ASANO Masahiro in http://lkml.org/lkml/2005/12/21/334. v9fs_file_lock() will skip locks on file which has mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. Such a lock will be skipped during unlock and the machine will end up with a BUG in locks_remove_flock(). v9fs_file_lock() should skip the check for mandatory locks when unlocking a file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GFS2 tracks the number of revokes and unrevokes that are part of committed transactions via sd_log_commited_revoke. It is possible for one process to add revokes during its transaction, while another process unrevokes them during its transaction. If the second process finishes its transaction first, sd_log_commited_revoke will be decremented by the number of unrevokes that the second process did, without first being incremented by the number of revokes the first process did. This is fine, since all started transactions must be completed before the journal can be flushed. However, sd_log_commited_revoke is an unsigned integer, and log_refund() causes an assertion failure if it would go negative at the end of a transaction. This patch makes sd_log_commited_revoke a signed integer and allows it to go negative. __gfs2_log_flush() still checks that it mataches the actual number of revokes.

After looking at the anon_inode and its users it looks like the best solution is to just mark the anon_inode as S_PRIVATE so the security system will ignore it.

This is because of solaris expects find some data on another places, then curernt implementation save it. This patch fixes this issue. It is tested by me, and also Alex reported that it works for him.

* | | | | fs/ufs: recognize Solaris-specific file system stateAlex Viskovatoff2010-03-132-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent releases of Solaris set the fs_clean state of an unmounted UFS file system as FSLOG ("logging fs"). However, the Linux kernel currently does not recognize the value which represents this state. Thus, attempting to mount such a file system rw produces the message kernel: ufs_read_super: can't grok fs_clean 0xfffffffd and the file system is mounted read-only. This patch makes the kernel recognize that value.

* | | | | fs: buffer_head: remove kmem_cache constructor to reduce memory usage under slubRichard Kennedy2010-03-131-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using slub, having a kmem_cache constructor forces slub to add a free pointer to the size of the cached object, which can have a significant impact to the number of small objects that can fit into a slab. As buffer_head is relatively small and we can have large numbers of them, removing the constructor is a definite win. On x86_64 removing the constructor gives me 39 objects/slab, 3 more than without the patch. And on x86_32 73 objects/slab, which is 9 more. As alloc_buffer_head() already initializes each new object there is very little difference in actual code run.
