* VFS: Fix another open intent OopsTrond Myklebust2006-04-19

* [PATCH] Make most file operations structs in fs/ constArjan van de Ven2006-03-28
| | | | | | | | | | | | | | This is a conversion to make the various file_operations structs in fs/ const. Basically a regexp job, with a few manual fixups The goal is both to increase correctness (harder to accidentally write to shared datastructures) and reducing the false sharing of cachelines with things that get dirty in .data (while .rodata is nicely read only and thus cache clean) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * NFSv4: Dont list system.nfs4_acl for filesystems that don't support it.J. Bruce Fields2006-03-20
| | | | | | | | | | | | | | | | | | | | Thanks to Frank Filz for pointing out that we list system.nfs4_acl extended attribute even on filesystems where we don't actually support nfs4_acl. This is inconsistent with the e.g. ext3 POSIX ACL behaviour, and seems to annoy cp. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * NFS: Fix a race in nfs_sync_inode()Trond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kudos to Neil Brown for spotting the problem: "in nfs_sync_inode, there is effectively the sequence: nfs_wait_on_requests nfs_flush_inode nfs_commit_inode This seems a bit racy to me as if the only requests are on the ->commit list, and nfs_commit_inode is called separately after nfs_wait_on_requests completes, and before nfs_commit_inode start (say: by nfs_write_inode) then none of these function will return >0, yet there will be some pending request that aren't waited for." The solution is to search for requests to wait upon, search for dirty requests, and search for uncommitted requests while holding the nfsi->req_lock The patch also cleans up nfs_sync_inode(), getting rid of the redundant FLUSH_WAIT flag. It turns out that we were always setting it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need to set PG_private for readahead pages, since they never get unlocked while I/O is in progress. However there is a small race in nfs_readpage_release() whereby the page may be unlocked, and have PG_private set. Fix is to have PG_private set only for the case of writes... Also fix a bug in nfs_clear_page_writeback(): Don't attempt to clear the radix_tree tag if we've already deleted the radix tree entry. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | If the callback daemon is signalled, but is unable to exit because it still has users, then we need to flush signals. If not, then svc_recv() can never sleep, and so we hang. If we flush signals, then we also have to be prepared to resend them when we want the thread to exit.

| * NFS: O_DIRECT async IO may lose contextTrond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | The struct nfs_direct_req currently keeps a pointer to the file descriptor without referencing it. This may cause problems if the parent process is killed. The nfs_open_context should normally have all the information that we're currently using the filp for, and unlike fput(), is safe to release from an rpciod process context.

| * nfs: Use UNSTABLE + COMMIT for NFS O_DIRECT writesTrond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently NFS O_DIRECT writes use FILE_SYNC so that a COMMIT is not necessary. This simplifies the internal logic, but this could be a difficult workload for some servers. Instead, let's send UNSTABLE writes, and after they all complete, send a COMMIT for the dirty range. After the COMMIT returns successfully, then do the wake_up or fire off aio_complete(). Test plan: Async direct I/O tests against Solaris (or any server that requires committed unstable writes).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three atomic_t variables cause a lot of bus locking. Because they are all used in the same places in the code, just use a single spin lock.

This will enable us to add support for aio in this path. Temporarily we will lose the ability to do UNSTABLE writes followed by a COMMIT in the direct write path.

Instead of having the NFSv2/v3/v4-specific code set up the RPC callback ops, we allow the original caller to do so. This allows for more flexibility w.r.t. how to set up and tear down the nfs_write_data structure while still allowing the NFSv3/v4 code to perform error handling. The greater flexibility is needed by the asynchronous O_DIRECT code, which wants to be able to hold on to the original nfs_write_data structures after the WRITE RPC call has completed in order to be able to replay them if the COMMIT call determines that the server has rebooted.
