* ocfs2: Fix deadlock when allocating pageJan Kara2010-09-081-1/+1
| | | | | | | | | | | | | We cannot call grab_cache_page() when holding filesystem locks or with a transaction started as grab_cache_page() calls page allocation with GFP_KERNEL flag and thus page reclaim can recurse back into the filesystem causing deadlocks or various assertion failures. We have to use find_or_create_page() instead and pass it GFP_NOFS as we do with other allocations.

* | Ocfs2: Optimize ocfs2 truncate to use ocfs2_remove_btree_range() instead.Tristan Ye2010-05-181-528/+157
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Truncate is just a special case of punching holes(from new i_size to end), we therefore could take advantage of the existing ocfs2_remove_btree_range() to reduce the comlexity and redundancy in alloc.c. The goal here is to make truncate more generic and straightforward. Several functions only used by ocfs2_commit_truncate() will smiply be removed. ocfs2_remove_btree_range() was originally used by the hole punching code, which didn't take refcount trees into account (definitely a bug). We therefore need to change that func a bit to handle refcount trees. It must take the refcount lock, calculate and reserve blocks for refcount tree changes, and decrease refcounts at the end. We replace ocfs2_lock_allocators() here by adding a new func ocfs2_reserve_blocks_for_rec_trunc() which accepts some extra blocks to reserve. This will not hurt any other code using ocfs2_remove_btree_range() (such as dir truncate and hole punching). I merged the following steps into one patch since they may be logically doing one thing, though I know it looks a little bit fat to review. 1). Remove redundant code used by ocfs2_commit_truncate(), since we're moving to ocfs2_remove_btree_range anyway. 2). Add a new func ocfs2_reserve_blocks_for_rec_trunc() for purpose of accepting some extra blocks to reserve. 3). Change ocfs2_prepare_refcount_change_for_del() a bit to fit our needs. It's safe to do this since it's only being called by truncate. 4). Change ocfs2_remove_btree_range() a bit to take refcount case into account. 5). Finally, we change ocfs2_commit_truncate() to call ocfs2_remove_btree_range() in a proper way. The patch has been tested normally for sanity check, stress tests with heavier workload will be expected. Based on this patch, fixing the punching holes bug will be fairly easy.

* ocfs2: Make ocfs2_extend_trans() really extend.Tao Ma2010-05-061-21/+9
| | | | | | | | | | | | | | | In ocfs2, we use ocfs2_extend_trans() to extend a journal handle's blocks. But if jbd2_journal_extend() fails, it will only restart with the the new number of blocks. This tends to be awkward since in most cases we want additional reserved blocks. It makes our code harder to mantain since the caller can't be sure all the original blocks will not be accessed and dirtied again. There are 15 callers of ocfs2_extend_trans() in fs/ocfs2, and 12 of them have to add h_buffer_credits before they call ocfs2_extend_trans(). This makes ocfs2_extend_trans() really extend atop the original block count. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

* ocfs2: Make ocfs2_journal_dirty() void.Joel Becker2010-05-061-130/+34
| | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the alloc_space, free_space, reserve_space, claim_space and release_rsv dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Move shared logic into the common __dquot_alloc_space, dquot_claim_space_nodirty and __dquot_free_space low-level methods, and rationalize the wrappers around it to move as much as possible code into the common block for CONFIG_QUOTA vs not.

| | | | | | | | | | | | | | | | | | | | | | | | | | ocfs2_mark_extent_written actually does the following things: 1. check the parameters. 2. initialize the left_path and split_rec. 3. call __ocfs2_mark_extent_written. it will do: 1) check the flags of unwritten 2) do the real split work. The whole process is packed tightly somehow. So this patch will abstract 2 different functions so that future b-tree operation can work with it. 1. __ocfs2_split_extent will accept path and split_rec and do the real split work. 2. ocfs2_change_extent_flag will accept a new flag and initialize path and split_rec. So now ocfs2_mark_extent_written will do: 1. check the parameters. 2. call ocfs2_change_extent_flag. 1) initalize the left_path and split_rec. 2) check whether the new flags conflict with the old one. 3) call __ocfs2_split_extent to do the split.
