Subject: LU-16589 tests: add sanity/31l to test ln command
X-Git-Tag: 2.15.55~28
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=e998d21caf99e32495950219e88dd9e7f981363e;p=fs%2Flustre-release.git

LU-16589 tests: add sanity/31l to test ln command

This patch adds a new subtest sanity/31l to test
hard-linking a file to a target direcory that has
trailing "/".

The subtest will be skipped if the coreutils version
>= 8.31 and kernel version < 5.18 because the
coreutils commit v8.30-18-g571f63f5010b reveals
a kernel issue, which is fixed by kernel commit
v5.18-rc2-188-gb3d4650d82c7.
