* NFSv4: Fix an Oops in nfs_do_expire_all_delegationsTrond Myklebust2006-01-061-4/+2
| | | | | | If the loop errors, we need to exit. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Ensure DELEGRETURN returns attributesTrond Myklebust2006-01-061-2/+0
| | | | | | | | Upon return of a write delegation, the server will almost always bump the change attribute. Ensure that we pick up that change so that we don't invalidate our data cache unnecessarily. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Ensure change attribute returned by GETATTR callback conforms to specTrond Myklebust2006-01-061-0/+1
| | | | | | | | | | | According to RFC3530 we're supposed to cache the change attribute at the time the client receives a write delegation. If the inode is clean, a CB_GETATTR callback by the server to the client is supposed to return the cached change attribute. If, OTOH, the inode is dirty, the client should bump the cached change attribute by 1. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* [PATCH] kfree cleanup: fsJesper Juhl2005-11-071-2/+1
| | | | | | | | | | This is the fs/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in fs/. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* NFSv4: Recover locks too when returning a delegationTrond Myklebust2005-11-041-2/+36
| | | | | | | | | | Delegations allow us to cache posix and BSD locks, however when the delegation is recalled, we need to "flush the cache" and send the cached LOCK requests to the server. This patch sets up the mechanism for doing so. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Return delegation upon rename or removal of file.Trond Myklebust2005-10-181-1/+1

* [PATCH] NFS: Fix cache consistency racesTrond Myklebust2005-10-171-0/+4
| | | | | | | | | | | | If the data cache has been marked as potentially invalid by nfs_refresh_inode, we should invalidate it rather than assume that changes are due to our own activity. Also ensure that we always start with a valid cache before declaring it to be protected by a delegation.

* [PATCH] NFS: Header file cleanup...Trond Myklebust2005-06-221-0/+1

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
