qemu-img: mandate argument to 'qemu-img check --repair'
qemu-img check --repair option accepts an argument. The argument to --repair switch can either be 'all' or 'leak'. Fix the long option to mandate argument with --repair switch. The patch fixes following segmentation fault Core was generated by `qemu-img check -f qcow2 --repair all t.qcow2'. Program terminated with signal 11, Segmentation fault. 0 in img_check (argc=6, argv=0x7fffab9b8a10) at qemu-img.c:588 588 if (!strcmp(optarg, "leaks")) { (gdb) bt 0 img_check (argc=6, argv=0x7fffab9b8a10) at qemu-img.c:588 1 __libc_start_main () from /lib/x86_64-linux-gnu/libc.so.6 2 _start () (gdb) Signed-off-by: Prasad Joshi <prasadjoshi.linux@gmail.com> Reviewed-by: Leandro Dorileo <l@dorileo.org> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
