fs/9p: use fscache mutex rather than spinlock

2016-01-09T07:57:21+00:00

We may sleep inside a the lock, so use a mutex rather than spinlock. Signed-off-by: Sasha Levin Signed-off-by: Al Viro

9p: don't bother with __getname() in ->follow_link()

2015-05-11T02:18:19+00:00

We copy there a kmalloc'ed string and proceed to kfree that string immediately after that. Easier to just feed that string to nd_set_link() and _not_ kfree it until ->put_link() (which becomes kfree_put_link() in that case). Signed-off-by: Al Viro

9p: kerneldoc warning fixes

2015-03-20T14:34:41+00:00

options argument was removed from v9fs_session_info in commit 4b53e4b50077 ("9p: remove unnecessary v9fses->options which duplicates the mount string") iov and nr_segs were removed from v9fs_direct_IO in commit d8d3d94b80aa ("pass iov_iter to ->direct_IO()") Cc: Eric Van Hensbergen Cc: Ron Minnich Cc: Latchesar Ionkov Cc: v9fs-developer@lists.sourceforge.net Signed-off-by: Fabian Frederick Signed-off-by: Dominique Martinet Signed-off-by: Eric Van Hensbergen

9P: introduction of a new cache=mmap model.

2014-01-10T15:20:51+00:00

- Add cache=mmap option - Make mmap read-write while keeping it as synchronous as possible - Build writeback fid on mmap creation if it is writable Signed-off-by: Dominique Martinet Signed-off-by: Eric Van Hensbergen

9p: Modify struct v9fs_session_info to use a kuids and kgids

2013-02-12T11:19:33+00:00

Change struct v9fs_session_info and the code that popluates it to use kuids and kgids. When parsing the 9p mount options convert the dfltuid, dflutgid, and the session uid from the current user namespace into kuids and kgids. Modify V9FS_DEFUID and V9FS_DEFGUID to be kuid and kgid values. Cc: Eric Van Hensbergen Cc: Ron Minnich Cc: Latchesar Ionkov Signed-off-by: "Eric W. Biederman"

stop passing nameidata to ->lookup()

2012-07-14T12:34:32+00:00

Just the flags; only NFS cares even about that, but there are legitimate uses for such argument. And getting rid of that completely would require splitting ->lookup() into a couple of methods (at least), so let's leave that alone for now... Signed-off-by: Al Viro

fs/9p: Always ask new inode in create

2011-07-23T14:32:50+00:00

This make sure we don't end up reusing the unlinked inode object. The ideal way is to use inode i_generation. But i_generation is not available in userspace always. Signed-off-by: Aneesh Kumar K.V Signed-off-by: Eric Van Hensbergen

fs/9p: When doing inode lookup compare qid details and inode mode bits.

2011-07-23T14:32:48+00:00

This make sure we don't use wrong inode from the inode hash. The inode number of the file deleted is reused by the next file system object created and if we only use inode number for inode hash lookup we could end up with wrong struct inode. Also compare inode generation number. Not all Linux file system provide st_gen in userspace. So it could be 0; Signed-off-by: Aneesh Kumar K.V Signed-off-by: Eric Van Hensbergen

9p: revert tsyncfs related changes

2011-04-15T20:26:14+00:00

Now that we use write_inode to flush server cache related to fid, we don't need tsyncfs either fort dotl or dotu protocols. For dotu this helps to do a more efficient server flush. Signed-off-by: Aneesh Kumar K.V Signed-off-by: Venkateswararao Jujjuri Signed-off-by: Eric Van Hensbergen

fs/9p: Add v9fs_dentry2v9ses

2011-03-22T20:43:36+00:00

Add the new static inline and use the same Signed-off-by: Aneesh Kumar K.V Signed-off-by: Venkateswararao Jujjuri Signed-off-by: Eric Van Hensbergen
