[PATCH] btrfs: remove useless comments

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]



Remove comments from the new test template that are not relevant once
the test case is written:

- commented out common.filters (no filters used)
- Import common functions.
- real QA test starts here
- Modify as appropriate.
- get standard environment, filters and checks
