Some tests use killall command, but killall may not exist. We should check whether killall exists or not. Signed-off-by: Masayoshi Mizuma <m.mizuma@jp.fujitsu.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# FS QA Test No. xfs/011
|
|
#
|
|
# Test the xfs log reservation mechanism for leaks. Run an fsstress workload to
|
|
# include a variety of fs operations, freeze the filesystem and verify that
|
|
# there are no oustanding reservations against the log.
