afs: convert to new aops

2008-10-16T18:21:48Z

Cannot assume writes will fully complete, so this conversion goes the easy way and always brings the page uptodate before the write. [dhowells@redhat.com: style tweaks] Signed-off-by: Nick Piggin Acked-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

AFS: implement file locking

2007-07-16T16:05:43Z

Implement file locking for AFS. Signed-off-by: David Howells Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sendfile: remove .sendfile from filesystems that use generic_file_sendfile()

2007-07-10T06:04:13Z

They can use generic_file_splice_read() instead. Since sys_sendfile() now prefers that, there should be no change in behaviour. Signed-off-by: Jens Axboe

AFS: fix a couple of problems with unlinking AFS files

2007-05-11T15:29:32Z

Fix a couple of problems with unlinking AFS files. (1) The parent directory wasn't being updated properly between unlink() and the following lookup(). It seems that, for some reason, invalidate_remote_inode() wasn't discarding the directory contents correctly, so this patch calls invalidate_inode_pages2() instead on non-regular files. (2) afs_vnode_deleted_remotely() should handle vnodes that don't have a source server recorded without oopsing.

AFS: implement basic file write support

2007-05-09T19:30:50Z

Implement support for writing to regular AFS files, including: (1) write (2) truncate (3) fsync, fdatasync (4) chmod, chown, chgrp, utime. AFS writeback attempts to batch writes into as chunks as large as it can manage up to the point that it writes back 65535 pages in one chunk or it meets a locked page. Furthermore, if a page has been written to using a particular key, then should another write to that page use some other key, the first write will be flushed before the second is allowed to take place. If the first write fails due to a security error, then the page will be scrapped and reread before the second write takes place. If a page is dirty and the callback on it is broken by the server, then the dirty data is not discarded (same behaviour as NFS). Shared-writable mappings are not supported by this patch.

AFS: AFS fixups

2007-05-09T19:30:50Z

Make some miscellaneous changes to the AFS filesystem: (1) Assert RCU barriers on module exit to make sure RCU has finished with callbacks in this module. (2) Correctly handle the AFS server returning a zero-length read. (3) Split out data zapping calls into one function (afs_zap_data). (4) Rename some afs_file_*() functions to afs_*() where they apply to non-regular files too. (5) Be consistent about the presentation of volume ID:vnode ID in debugging output.

[AFS]: Add "directory write" support.

2007-04-26T22:59:35Z

Add support for the create, link, symlink, unlink, mkdir, rmdir and rename VFS operations to the in-kernel AFS filesystem. Also: (1) Fix dentry and inode revalidation. d_revalidate should only look at state of the dentry. Revalidation of the contents of an inode pointed to by a dentry is now separate. (2) Fix afs_lookup() to hash negative dentries as well as positive ones. Signed-off-by: David Howells Signed-off-by: David S. Miller

[AFS]: Add security support.

2007-04-26T22:57:07Z

Add security support to the AFS filesystem. Kerberos IV tickets are added as RxRPC keys are added to the session keyring with the klog program. open() and other VFS operations then find this ticket with request_key() and either use it immediately (eg: mkdir, unlink) or attach it to a file descriptor (open).

[AF_RXRPC]: Make the in-kernel AFS filesystem use AF_RXRPC.

2007-04-26T22:55:03Z

Make the in-kernel AFS filesystem use AF_RXRPC instead of the old RxRPC code. Signed-off-by: David Howells Signed-off-by: David S. Miller

[AFS]: Clean up the AFS sources

2007-04-26T22:49:28Z

Clean up the AFS sources. Also remove references to AFS keys. RxRPC keys are used instead. Signed-off-by: David Howells Signed-off-by: David S. Miller
