On xfs filesystem, the following patch fixed system crash caused by
this race, but it introduced the __xfs_get_blocks() warning when the
race occurred:
04197b3 ("xfs: don't BUG() on mixed direct and mapped I/O")
On upstream kernel, the fix patch was cleared by:
acdda3a ("xfs: use iomap_dio_rw")
When the fix patch was applied and not cleared(e.g, on RHEL7.4), this
case triggered the __xfs_get_blocks() warning as expected. Moreover,
generic/095 may reproduce the same warning occasionally. So we could
add __xfs_get_blocks() into _filter_xfs_dmesg.
