[LTP] [PATCH V6 00/10] Add new LTP tests related to fsmount family of syscalls

[Viresh Kumar]

Hello,

Here is the sixth version of these patches.  This is tested on both ARM
and X86 platforms now and no more errors are seen with it.

V5->V6:
- A new implementation of tst_is_mounted() and a new helper
  tst_is_mounted_at_tmpdir().
- Add cleanup() callback in fsconfig01.c
- Call umount() only if tst_is_mounted_at_tmpdir() passes.
- Call close() in fsopen_supported_by_kernel().
- Use /dev/foo instead of /dev/sda1

V4->V5:
- s/TBROK/TFAIL/ in run(int n) callbacks.
- Many conversions like TEST(fd = fsopen());
- A new implementation of tst_is_mounted().
- fspick.h created to take care of duplicate code.
- tmp directory not removed from code as that will be auto done anyway.
- Other minor improvements.

V3->V4:
- Only the first patch was resent after fixing git log and minor code
  modifications.

V2->V3:
- Fix errors with xfs.
- Add macros to define test names.
- Continue with multiple iteration tests on failures, instead of
  returning early.
- Set value of is_mounted in open_tree patch.
- Rename tst_ismount() and make it return 1 on success.
- Fix various formatting issues.
- Add all reviewed/ack tags.

V1->V2:
- Lots of changes, really :)
- Rebased over Zorro's work with fsmount.
- The success tests are modified to test all possible flags, attributes
  as well.
- Create tst_ismount() and fsopen_supported_by_kernel() helpers.
- Verify if mount is successful or not using tst_ismount().
- Remove min_kver and instead check if older kernels have patches
  backported or not.
- Test on multiple filesystems.
- Better handling of failures during setup/run callbacks.
- One of the patches around fsmount.h is already merged, dropped it now.
- Other minor cleanups.
