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: Fix revalidate to return correct value

2011-04-15T20:26:13+00:00

revalidate should return > 0 on success. Also return 0 on ENOENT
to force do_revalidate to return NULL dentry;

9p: use the updated offset given by generic_write_checks

2011-03-22T21:32:49+00:00

Without this fix, even if a file is opened in O_APPEND mode, data will be
written at current file position instead of end of file.

fs/9p: Attach writeback_fid on first open with WR flag

We don't need writeback fid if we are only doing O_RDONLY open

fs/9p: Open writeback fid in O_SYNC mode

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

Older version of protocol don't support tsyncfs operation.
So for them force a O_SYNC flag on the server

fs/9p: Use truncate_setsize instead of vmtruncate

2011-03-22T20:43:35+00:00

convert vmtruncate usage to truncate_setsize. We also writeback
all dirty pages before doing 9p operations and on success call truncate_setsize.
This ensure that we continue sanely on failed truncate on the server. The
disadvantage is that we are now going to write back the content that get
thrown away later as a part of truncate.
