The nfsv4 protocol's lock operation, in the case of a conflict, returns information about the conflicting lock. It's unclear how clients can use this, so for now we're not going so far as to add a filesystem method that can return a conflicting lock, but we may as well return something in the local case when it's easy to.

Factor out the code that switches between generic and filesystem-specific lock methods; eventually we want to call this from lock managers (lockd and nfsd) too; currently they only call the generic methods. This patch does that for test_lock. Note that this hasn't been necessary until recently, because the few filesystems that define ->lock() (nfs, cifs...) aren't exportable via NFS. However GFS (and, in the future, other cluster filesystems) need to implement their own locking to get cluster-coherent locking, and also want to be able to export locking to NFS (lockd and NFSv4). So we accomplish this by factoring out code such as this and exporting it for the use of lockd and nfsd. Signed-off-by: N"J. Bruce Fields" <bfields@citi.umich.edu>

The file_lock argument to ->lock is used to return the conflicting lock when found. There's no reason for the filesystem to return any private information with this conflicting lock, but nfsv4 is.

If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must ensure that the PG_writeback flag is cleared. Also ensure that we actually own the PG_writeback flag whenever we schedule a new writeback by making nfs_set_page_writeback() return the value of test_set_page_writeback(). The PG_writeback page flag ends up replacing the functionality of the PG_FLUSHING nfs_page flag, so we rip that out too.

Commit f50b6f86 introduced a race in autofs4 between autofs_lookup_unhashed() and autofs_dentry_release(). autofs_dentry_release() ends up clearing the ->dentry and ->inode members of autofs_info before removing it from the rehash list. The list is protected by the rehash lock in both functions, but since autofs_dentry_release() starts tearing the autofs_info struct down before removing it from the list, autofs_lookup_unhashed() can get a autofs_info with a NULL dentry. This patch moves the clearing of ->dentry and ->inode after the removal from the rehash list.

It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups.

Revert e92a4d59. Dmitry points out "When we block_prepare_write() failed while ext3_prepare_write() we jump to "failure" label and call ext3_prepare_failure() witch search last mapped bh and invoke commit_write untill it. This is wrong!! because some bh from begining to the last mapped bh may be not uptodate. As a result we commit to disk not uptodate page content witch contains garbage from previous usage." and "Unexpected file size increasing." Call trace the same as it was in first issue but result is different. For example we have file with i_size is zero. we want write two blocks , but fs has only one free block. ->ext3_prepare_write(...from == 0, to == 2048) retry: ->block_prepare_write() == -ENOSPC# we failed but allocated one block here. ->ext3_prepare_failure() ->commit_write( from == 0, to == 1024) # after this i_size becomes 1024 :) if (ret == -ENOSPC && ext3_should_retry_alloc(inode->i_sb, &retries)) goto retry; Finally when all retries will be spended ext3_prepare_failure return -ENOSPC, but i_size was increased and later block trimm procedures can't help here. We don't appear to have the horsepower to fix these issues, so let's put things back the way they were for now.

Stealing pages with splice is problematic because we cannot just insert an uptodate page into the pagecache and hope the filesystem can take care of it later. We also cannot just ClearPageUptodate, then hope prepare_write does not write anything into the page, because I don't think prepare_write gives that guarantee. Remove support for SPLICE_F_MOVE for now. If we really want to bring it back, we might be able to do so with a the new filesystem buffered write aops APIs I'm working on. If we really don't want to bring it back, then we should decide that sooner rather than later, and remove the flag and all the stealing infrastructure before anybody starts using it.

This bug was seen on ppc64, but it could have occurred on any architecture with a page size of 64k or above. The problem is that in fs/binfmt_elf.c:randomize_stack_top() randomizes the stack to within 0x7ff pages. On 4k page machines, this is 8MB; on 64k page boxes, this is 128MB. The problem is that the new binary layout (selected in arch_pick_mmap_layout) places the mapping segment 128MB or the stack rlimit away from the top of the process memory, whichever is larger. If you chose an rlimit of less than 128MB (most defaults are in the 8Mb range) then you can end up having your entire stack randomized away. The fix is to make randomize_stack_top() only steal at most 8MB, which this patch does. However, I have to point out that even with this, your stack rlimit might not be exactly what you get if it's > 128MB, because you're still losing the random offset of up to 8MB. The true fix should be to leave an explicit gap for the randomization plus a buffer when determining mmap_base, but that would involve fixing all the architectures.
