9p: revert tsyncfs related changes

2011-04-15T20:26:14Z

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: Open writeback fid in O_SYNC mode

2011-03-22T20:43:36Z

Older version of protocol don't support tsyncfs operation. So for them force a O_SYNC flag on the server Signed-off-by: Aneesh Kumar K.V Signed-off-by: Venkateswararao Jujjuri Signed-off-by: Eric Van Hensbergen

9p: potential ERR_PTR() dereference

2010-08-30T15:35:28Z

p9_client_walk() can return error values if we run out of space or there is a problem with the network. Signed-off-by: Dan Carpenter Signed-off-by: Eric Van Hensbergen

fs/9p: Prevent parallel rename when doing fid_lookup

2010-08-02T19:28:35Z

During fid lookup we need to make sure that the dentry->d_parent doesn't change so that we can safely walk the parent dentries. To ensure that we need to prevent cross directory rename during fid_lookup. Add a per superblock rename_sem rw_semaphore to prevent parallel fid lookup and rename.

fs/9p: Pass the correct user credentials during attach

2010-08-02T19:25:08Z

We need to make sure we pass the right uid value during attach. dotl is similar to dotu in this regard. Without this mapped security model on dotl doesn't work Signed-off-by: Aneesh Kumar K.V Signed-off-by: Eric Van Hensbergen
