Issue:
--------------------------
xfstest fails with sanity checks on seek operations
# uname -a
Linux ltc-tuleta12 4.10.0-21-generic #23~16.04.1-Ubuntu SMP Tue May 2
12:54:57 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
Steps to reproduce:
----------------------------------------
1. Create a loop device with xfs filesystem
2. git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git; cd
xfstests-dev
3. make
4. Create a local.config for running with created loop device
5. Run xfstests-dev test : ./check tests/generic/285 or ./check
tests/generic/436
The test 285 fails with following
...
...

== Comment: #6 - Harish Sriram
commit 5375023ae1266553a7baa0845e82917d8803f48c
Author: Jan Kara <j...@suse.cz>
Date: Thu May 18 16:36:22 2017 -0700
xfs: Fix missed holes in SEEK_HOLE implementation
XFS SEEK_HOLE implementation could miss a hole in an unwritten extent as
can be seen by the following command:
xfs_io -c "falloc 0 256k" -c "pwrite 0 56k" -c "pwrite 128k 8k"
-c "seek -h 0" file
wrote 57344/57344 bytes at offset 0
56 KiB, 14 ops; 0.0000 sec (49.312 MiB/sec and 12623.9856 ops/sec)
wrote 8192/8192 bytes at offset 131072
8 KiB, 2 ops; 0.0000 sec (70.383 MiB/sec and 18018.0180 ops/sec)
Whence Result
HOLE 139264
Where we can see that hole at offset 56k was just ignored by SEEK_HOLE
implementation. The bug is in xfs_find_get_desired_pgoff() which does
not properly detect the case when pages are not contiguous.
Fix the problem by properly detecting when found page has larger offset
than expected.

The above commit fixes the generic/436 test, but generic/285 still FAILS.
The generic/285 failure is reproducible on most P8/P9 systems.
