With upstream commit 332391a9935d ("fs: Fix page cache inconsistency
when mixing buffered and AIO DIO"), ext4 (and probably other
non-iomap based filesystems) need a _check_dmesg() whitelist entry
for a new WARN in dio_complete() -- generic/095 and 247 trigger a
dio_complete() splat pretty reliably for me.
Add dio_complete() entry to _filter_xfs_dmesg(), rename it and use
it unconditionally in generic/095, 224, 247 and 446.
[eguan: source common/filter too in generic/446]

# FS QA Test No. 224

|
# Delayed allocation at ENOSPC test

|
|
# Derived from a test case from Lachlan McIlroy and improved to
|
|
# reliably trigger a BUG in xfs_get_blocks(). Despite this XFS
|
|
# focus, the test can to run on any filesystem to exercise ENOSPC
|
|
# behaviour.
