[PATCH v2] fstests: remove tmp files properly

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



Some tests and common helpers don't properly clean up tmp files and
leave them behind in /tmp dir, and these tmp files are accumulating
over time.

v2:
- let common helper functions do their cleanups by themselves,
  no hidden usage of $tmp
- only remove/adjust necessary files, don't do large scale test updates
