2010-03-05pass writeback_control to ->write_inodeChristoph Hellwig
This gives the filesystem more information about the writeback that is happening. Trond requested this for the NFS unstable write handling, and other filesystems might benefit from this too by beeing able to distinguish between the different callers in more detail. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-03-05make sure data is on disk before calling ->write_inodeChristoph Hellwig
Similar to the fsync issue fixed a while ago in commit 2daea67e966dc0c42067ebea015ddac6834cef88 we need to write for data to actually hit the disk before writing out the metadata to guarantee data integrity for filesystems that modify the inode in the data I/O completion path. Currently XFS and NFS handle this manually, and AFS has a write_inode method that does nothing but waiting for data, while others are possibly missing out on this. Fortunately this change has a lot less impact than the fsync change as none of the write_inode methods starts data writeout of any form by itself.

2010-03-05Get rid of symlink body copyingAl Viro
Now that nd->last stays around until ->put_link() is called, we can just postpone that ->put_link() in do_filp_open() a bit and don't bother with copying. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-05bail out with ELOOP earlier in do_link loopAl Viro
If we'd passed through 32 trailing symlinks already, there's no sense following the 33rd - we'll bail out anyway. Better bugger off earlier. It *does* change behaviour, after a fashion - if the 33rd happens to be a procfs-style symlink, original code *would* allow it. This one will not. Cry me a river if that hurts you. Please, do. And post a video of that, while you are at it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-05postpone __putname() until after do_last()Al Viro
Since do_last() doesn't mangle nd->last_name, we can safely postpone __putname() done in handling of trailing symlinks until after the call of do_last() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-05gut do_filp_open() a bit more (do_last separation)Al Viro
Brute-force separation of stuff reachable from do_last: with the exception of do_link:; just take all that crap to a helper function as-is and have it tell the caller if it has to go to do_link. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-03-05beginning to untangle do_filp_open()Al Viro
That's going to be a long and painful series. The first step: take the stuff reachable from 'ok' label in do_filp_open() into a new helper (finish_open()). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-04ext4: Fix the NULL reference in double_down_write_data_sem()Akira Fujita
If EXT4_IOC_MOVE_EXT ioctl is called with NULL donor_fd, fget() in ext4_ioctl() gets inappropriate file structure for donor; so we need to do this check earlier, before calling double_down_write_data_sem().
