Unless someone else would come up with better idea, you can always do:

git bisect start
git bisect bad 44e6f84e3597905816a0440e7218d2ed072120da
git bisect start 741b2252a5e14d6c60a913c77a6099abe73a854a
Bisecting: 2021 revisions left to test after this
[739cafd316235fc55463849e80710f2ca308b9ae] [XFS] fix PBF_NONE handling
make
...
[reboot]
git bisect good # if it boots
or
git bisect bad # if it doesn't
make
...
[reboot]

"2021" suggests that it would take 10 or so recompiles to identify bad
commit.
