btrfs: return EINVAL if start > total_bytes in fitrim ioctl We should retirn EINVAL if the start is beyond the end of the file system in the btrfs_ioctl_fitrim(). Fix that by adding the appropriate check for it. Also in the btrfs_trim_fs() it is possible that len+start might overflow if big values are passed. Fix it by decrementing the len so that start+len is equal to the file system size in the worst case. Signed-off-by: Lukas Czerner <lczerner@redhat.com>
