| | | | | | | | | | | | | | | But keep it as a dprintk The message can be generated in a quite normal situation: If a 'lock' request is interrupted, then the lock client needs to record that the server has the lock, incase it does. When we come the unlock, the server might say it doesn't, even though we think it does (or might) and this generates the message.

* [PATCH] knfsd: Fix type mismatch with filldir_t used by nfsdNeilBrown2007-01-264-10/+13
| | | | | | | | | | | | | | | | | | | | | | nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now. Less internal (to nfsd) checking offset by more external checking, which is more important. Thanks to Gabriel Paubert <paubert@iram.es> for discovering this and providing an initial patch.

* [PATCH] knfsd: Don't mess with the 'mode' when storing a exclusive-create cookiePeter Staubach2007-01-261-16/+5
| | | | | | | | | | | | | | | | | | | | | NFS V3 (and V4) support exclusive create by passing a 'cookie' which can get stored with the file. If the file exists but has exactly the right cookie stored, then we assume this is a retransmit and the exclusive create was successful. The cookie is 64bits and is traditionally stored in the mtime and atime fields. This causes a problem with Solaris7 as negative mtime or atime confuse it. So we moved two bits into the mode word instead. But inherited ACLs sometimes overwrite the mode word on create, so this is a problem. So we give up and just store 62 of the 64 bits and assume that is close enough.

* [PATCH] knfsd: fix an NFSD bug with full sized, non-page-aligned readsNeilBrown2007-01-261-1/+2
| | | | | | | | | | | | | | | | | | NFSd assumes that largest number of pages that will be needed for a request+response is 2+N where N pages is the size of the largest permitted read/write request. The '2' are 1 for the non-data part of the request, and 1 for the non-data part of the reply. However, when a read request is not page-aligned, and we choose to use ->sendfile to send it directly from the page cache, we may need N+1 pages to hold the whole reply. This can overflow and array and cause an Oops. This patch increases size of the array for holding pages by one and makes sure that entry is NULL when it is not in use.

* [PATCH] i386 vDSO: use VM_ALWAYSDUMPRoland McGrath2007-01-261-3/+35
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes core dumps to include the vDSO vma, which is left out now. It removes the special-case core writing macros, which were not doing the right thing for the vDSO vma anyway. Instead, it uses VM_ALWAYSDUMP in the vma; there is no need for the fixmap page to be installed. It handles the CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from get_gate_vma after real vmas in the same way the /proc/PID/maps code does. This changes core dumps so they no longer include the non-PT_LOAD phdrs from the vDSO. I made the change to add them in the first place, but in turned out that nothing ever wanted them there since the advent of NT_AUXV. It's cleaner to leave them out, and just let the phdrs inside the vDSO image speak for themselves.

| | | | | | | | | | | | | | | | | | In __writeback_single_inode(), when we find a locked inode and we're not doing a data-integrity sync, we used to just skip writing entirely, since we didn't want to wait for the inode to unlock.

* Resurrect 'try_to_free_buffers()' VM hackeryLinus Torvalds2007-01-261-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not pretty, but it appears that ext3 with data=journal will clean pages without ever actually telling the VM that they are clean. This, in turn, will result in the VM (and balance_dirty_pages() in particular) to never realize that the pages got cleaned, and wait forever for an event that already happened. Technically, this seems to be a problem with ext3 itself, but it used to be hidden by 'try_to_free_buffers()' noticing this situation on its own, and just working around the filesystem problem. This commit re-instates that hack, in order to avoid a regression for the 2.6.20 release. This fixes bugzilla 7844: http://bugzilla.kernel.org/show_bug.cgi?id=7844 Peter Zijlstra points out that we should probably retain the debugging code that this removes from cancel_dirty_page(), and I agree, but for the imminent release we might as well just silence the warning too (since it's not a new bug: anything that triggers that warning has been around forever).

* | [PATCH] resierfs: avoid tail packing if an inode was ever mmappedVladimir Saveliev2007-01-232-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We observe soft lockups when doing heavy test which creates directory with a lot of direntries and deletes them.

The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account. Artem, BTW, thanks a lot for your valuable input! Signed-off-by: Vitaly Wool <vwool@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
