...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? Pretty please? :D
