[Bug 1199970] reaim-io-disk ext4 regression in 5.18 in mballoc

https://bugzilla.suse.com/show_bug.cgi?id=1199970 https://bugzilla.suse.com/show_bug.cgi?id=1199970#c4 --- Comment #4 from Jan Kara <jack@suse.com> --- OK, some updates after rather long time. The regression seems to be mostly triggered by reaim rapidly creating, fsyncing, and deleting small files. I was able to reproduce the regression using a simpler stress-unlink benchmark: stress-unlink -s -c 10000 -f 22528 16 0 /mnt Results with this benchmark are: AVG STDDEV mb_optimize_scan=0: 28.285800 0.156846 mb_optimize_scan=1: 30.896600 0.323324 -- You are receiving this mail because: You are on the CC list for the bug.
