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. 079
|
|
#
|
|
# Regression test for a bug in the log record checksum mechanism of XFS. Log
|
|
# records are checksummed during recovery and a warning or mount failure occurs
|
|
# on checksum verification failure. XFS had a bug where the checksum mechanism
|
|
# verified different parts of a record depending on the current log buffer size.
|
|
# This caused spurious checksum failures when a filesystem is recovered using a
|
|
# different log buffer size from when the filesystem crashed.
|
|
#
|
|
# Test that log recovery succeeds with a different log buffer size from when the
|
|
# filesystem crashed.
