[PATCH 0/3] afs: Fix directory size handling

From: David Howells

Hi Linus,

Could you apply these three fixes to AFS directory handling?

(1) Make sure that afs_read_dir() sees any increase in file size if the
file unexpectedly changed on the server (e.g. due to another client
making a change).

(2) Make afs_getattr() always return the server's dir file size, not the
locally edited one, so that pagecache eviction doesn't cause the dir
file size to change unexpectedly.

(3) Prevent afs_read_dir() from getting into an endless loop if the server
indicates that the directory file size is larger than expected.

The patches can be found here:

Thanks,
David
