Subject: LU-6622 tests: reduce chance of stat timeout in lnet-selftest
X-Git-Tag: 2.8.56~19
X-Git-Url: https://git.whamcloud.com/gitweb?a=commitdiff_plain;h=7bdee09c30d07a50082d9a2c08182f7f3f6ea47a;p=fs%2Flustre-release.git

LU-6622 tests: reduce chance of stat timeout in lnet-selftest

lst_end_session() calls 'lst show_error' before 'lst stop b' which
stops batched tests. Stat RPC sent by 'lst show_error' may timeout due
to network congestion cause by running batched tests. 'lst show_error'
reports stat RPC's timeout case, so that check_lst_err() detects that
errors were found and assumes that the test failed.
Stop batched tests before call to 'lst show_error' in order to reduce
chance of RCS timeout during 'lst show_error'.
