loop: don't clear LO_FLAGS_PARTSCAN on LOOP_SET_STATUS{,64}
LOOP_SET_STATUS{,64} can set a lot more flags than it is supposed to clear (the LOOP_SET_STATUS_CLEARABLE_FLAGS vs LOOP_SET_STATUS_SETTABLE_FLAGS defines should have been a hint..). Fix this by only clearing the bits in LOOP_SET_STATUS_CLEARABLE_FLAGS. Fixes: ae074d07a0e5 ("loop: move updating lo_flag s out of loop_set_status_from_info") Reported-by: kernel test robot <[email protected]> Signed-off-by: Christoph Hellwig <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jens Axboe <[email protected]>
