# FS QA Test No. btrfs/082
|
|
|
|
|
#
|
|
|
|
|
# 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
|
|
|
|
|
