I tried it and it still does take at least two minutes and tons of logs until even
udev scan finishes on a device with incorrect FEC attributes.

And once it is finished, dm-verity crashes on dm-device removal...

Could we please have all crucial fixes upstream? It seems that
FEC is really not usable for now.

This is what I run (32bit VM, Linus' git + your fix), dmesg below.

DEV_NAME=tst12414
DEV_DATA=/dev/sdb
DEV_HASH=/dev/sdc
DEV_FEC=/dev/sdd

dmsetup -r create $DEV_NAME --table "0 8 verity 1 $DEV_DATA $DEV_HASH 4096 4096 1 1 sha256 0000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000 8 use_fec_from_device $DEV_FEC fec_roots 16 fec_blocks 1 fec_start 1"
