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. 310

# Check if there are two threads,one keeps calling read() or lseek(), and
|
|
# the other calling readdir(), both on the same directory fd.

|
|
# Testing on ext3: with dir_index disabled results in the following
|
|
# dmesg output: (also occurs when testing ext2 and ext4)
|
|
#
|
|
# EXT3-fs error (device sdb): ext3_readdir: bad entry in directory #1134241:
|
|
# rec_len % 4 != 0 - offset=2704, inode=16973836, rec_len=12850, name_len=52

# EXT3-fs error (device sdb): ext3_readdir: bad entry in directory #1134241:
|
|
# directory entry across blocks - offset=1672, inode=16973836, rec_len=14132,
|
|
# name_len=57
|
|
#
|
|
# The filesystem mount option 'errors=' will define the behavior
|
|
# when an error is encountered. (see mount manpage)
|
|
#
|
|
# The test is based on a testcase from Li Zefan <lizefan@huawei.com>.
