| # 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 |
| # 800ee2247f483b6d05ed47ef3bbc90b56451746c |
