2012-07-31 | fault-injection: fix failcmd.sh warning | Akinobu Mita | 1 | -1/+1 | |
"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> | |||||
2012-07-30 | fault-injection: add tool to run command with failslab or fail_page_alloc | Akinobu Mita | 1 | -0/+219 | |
This adds tools/testing/fault-injection/failcmd.sh to run a command while injecting slab/page allocation failures via fault injection. Example: Run a command "make -C tools/testing/selftests/ run_tests" with injecting slab allocation failure. # ./tools/testing/fault-injection/failcmd.sh \ -- make -C tools/testing/selftests/ run_tests Same as above except to specify 100 times failures at most instead of one time at most by default. # ./tools/testing/fault-injection/failcmd.sh --times=100 \ -- make -C tools/testing/selftests/ run_tests Same as above except to inject page allocation failure instead of slab allocation failure. # env FAILCMD_TYPE=fail_page_alloc \ ./tools/testing/fault-injection/failcmd.sh --times=100 \ -- make -C tools/testing/selftests/ run_tests 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> |
