Subject: [linus:master] [cifs] 7c1ac89480: filebench.sum_operations/s
-19.4% regression
Hello,
kernel test robot noticed a -19.4% regression of filebench.sum_operations/s on:
commit: 7c1ac89480e8d5d34d38a868642216c8f05ee602 ("cifs: Enable large folio support")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: filebench
