If the dql_queued() function receives an invalid argument, WARN about it and continue, instead of crashing the kernel. This was raised by checkpatch, when I am refactoring this code (see following patch/commit) WARNING: Do not crash the kernel unless it is absolutely unavoidable--use WARN_ON_ONCE() plus recovery code (if feasible) instead of BUG() or variants Signed-off-by: Breno Leitao <leitao@debian.org> --- include/linux/dynamic_queue_limits.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
