[PATCH 0/3] RFC: log all i_size updates

[Christoph Hellwig]

Given the bug we recently had pop up on IRC about lost i_size updates
when writing out inodes during umount I think it's time to stop relying
on the writeback code to get these things right for us, and always
log the inode size updates normally.  Patches 1 and 2 are preparations
that should go into the tree anyway, and patch 3 switches us to directly
log the size updates from the I/O completion handler.
