Hello,

Here is the updated patch set for improving SEEK_DATA/SEEK_HOLE with page cache 
probing for unwritten
extents, it fixes a couple of issues according to Dave and Mark's review 
comments towards v6.

Changes from v7 to v6:

- xfs_lookup_buffer_offset(), remove page unlock out of it, fix comments for 
this routine.

- xfs_find_get_pgoff(), sample the next page index while the page is locked.

- xfs_seek_data()/xfs_seek_hole(), move extent state check up stuff to a loop 
in both routines.
