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

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
