fault-injection: fix failcmd.sh warning
"fault-injection: add tool to run command with failslab or fail_page_alloc" added tools/testing/fault-injection/failcmd.sh to make it easier to inject slab/page allocation failures by fault injection. failcmd.sh prints the following warning when running with arguments for command. # ./failcmd.sh echo aaa failcmd.sh: line 209: [: echo: binary operator expected aaa This warning is caused by an improper check whether at least one parameter is left after parsing command options. Fix it by testing the length of $1 instead of $@ Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
