5e8b9e6 btrfs: add regression test for remount with thread_pool resized
did weird things to _filter_mkfs; aside from broken indentation,
it also short-circuited the default non-xfs behavior, which was to
emit a default block & inode size. And that was all because btrfs/082
was using _filter_mkfs & not redirecting output away as per normal.
Granted, it's not super clear that _filter_mkfs serves this rather
unique purpose, but anyway...
And, while having this default seems to be of questionable value,
not emitting *anything* led to this on btrfs:
+./tests/generic/204: line 76: space / (isize + dbsize): division by 0 (error token is ")")
because those variables don't get set for btrfs, thanks to the
above commit.
So take out the use of _filter_mkfs in btrfs/082, and take out the
munging of _filter_mkfs which broke generic/204, and get things back
to something semi-sane.

|
# Regression test for a btrfs issue of resizing 'thread_pool' when
|
|
# remount the fs.
|
|
#
|
|
# This regression was introduced by the following linux kernel commit:
|
|
# btrfs: Added btrfs_workqueue_struct implemented ordered
|
|
# execution based on kernel workqueue
|
|
# 08a9ff3264181986d1d692a4e6fce3669700c9f8
|
|
# And it was fixed by the following linux kernel commit:
|
|
# btrfs: fix crash in remount(thread_pool=) case
|
|
