[PATCH v8 0/4] xfs: seek_data/seek_hole refinements

[Jeff Liu]

Hello,

Here is the updated patch set of refine xfs_seek_data/xfs_seek_hole with page cache lookup for unwritten extents.
Hopefully, this version is qualified to be merged. :)

Changes from v8 to v7:

- xfs_find_get_pgoff()
  . Sample the next page index without page lock.  Also, add comments to clarify why it's safe to check page->index without page lock.
  . Remove (pgoff_t) PAGEVEC_SIZE.

- xfs_seek_data()/xfs_seek_hole(), ASSERT(i > 1).
