Wong <djwong@xxxxxxxxxx> ...assuming you've run generic/521 and generic/522 (fsx) and generic/476 (fsstress) through the grinder for several days? And just for laughs, could you run those three (for an hour or two) with MKFS_OPTIONS='-m reflink=0,rmapbt=0 -d rtinherit=1 -r extsize=28k,rtdev=/dev/XXX' just to see how well multipage folios deal with 4k blocks allocated in chunks of 28k on the realtime device?
