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.

fs/9p: Prevent parallel rename when doing fid_lookup

2010-08-02T19:28:35+00:00

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

2010-08-02T19:25:08+00:00

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
