[LTP] [PATCH v4 0/6] Add support for .max_kver

[Petr Vorel]

Hi all,

[RFC]
Li suggested [1] to .min_kver > .max_kver should be rejected, or at
least reported as broken test metadata.

I decided to add check to metadata parser (that required to link
metaparse.c against libltp.a). Runtime check with TWARN would be also
good, but let's discuss that first (if not, I'll remove TODO from
tst_test.c). Hence this part is [RFC].

Hopefully it's the last version :).

Kind regards,
Petr

Changes v3->v4:
* creat07: execve04: does not use max_kver, instead:
  creat07: execve04: Remove version check, add linux-git
* New commits:
  - tst_kvercmp: Factor out error handling
  - tst_kvercmp: Factor out 2 kernels integer comparison
  - [RFC] make: Allow to add LTP library as a dependency for host
  - [RFC] metaparse: Check {min,max}_kver validity

Changes in 3rd commit
* Mention flag in doc/developers/writing_tests.rst
* Fix doc (agent):
- * on any stable release (test with ``min_kver = "7.1"`` runs also on kernel
+ * on any stable release (test with ``max_kver = "7.1"`` runs also on kernel
* Fix checkpatch style (agent):
-       for (i=0, dots=0; max_kver[i]; i++)
+       for (i = 0, dots = 0; max_kver[i]; i++)
