[PATCH 0/3] Annonate fstests with possible reasons for failure

[Amir Goldstein <amir73il@gmail.com>]

In a perfect worlds, tests are expected to pass, but we do not live in a
perfect world.

In reality, fstests are often merged before a fix is merged to Linus'
tree or before a fix to all fs is available [1][2].

We all know that day when we pull fstests upstream branch and get a
bunch of new test failures.

This series [3] adds several new ways to annotate tests to provide some
hints for testers about which tests are expected to pass on which fs
and or which kernel versions:

 _fixed_by_kernel_commit
 _known_issue_before_kernel
 _known_issue_on_fs

And a new run option SKIP_KNOWN_ISSUES=yes.

These annotation and run option are inspired by a similar feature in LTP.

These annotation could be used by testers to auto-generate expunge list
for testing stable kernels from the information in _fixed_by_kernel_commit
and _known_issue_before_kernel. This trivial task is left is an excercise.

Thanks,
Amir.
