Subject: LU-8790 test: Limit lock number by available inodes count
X-Git-Tag: 2.9.51~37
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=b4a26e92d74265f134d71ba8c22362e266d366f4

LU-8790 test: Limit lock number by available inodes count

For machines with big numbers of CPUs the count of files to create
is more than available inodes. So, the sanity::test_124b fails.

Test-Parameters: trivial
