Subject: [PATCH] btrfs-progs: Correct check_running_fs_exclop() return value References: bsc#1184481 check_running_fs_exclop() can return 1 when exclop is changed to "none" The ret is set by the return value of the select() operation. Checking the exclusive op changes just the exclop variable while ret is still set to 1. Set ret exclusively if exclop is set to BTRFS_EXCL_NONE. --- utils.c | 2 ++ 1 file changed, 2 insertions(+) --- a/utils.c +++ b/utils.c @@ -2743,6 +2743,8 @@ tv.tv_sec /= 2; ret = select(sysfs_fd + 1, NULL, NULL, &fds, &tv); exclop = get_fs_exclop(fd); + if (exclop == BTRFS_EXCLOP_NONE) + ret = 0; continue; } }
