Pull sysfs fix from Al Viro:
"Get rid of lockdep false positives around sysfs/overlayfs
syzbot has uncovered a class of lockdep false positives for setups
with sysfs being one of the backing layers in overlayfs. The root
cause is that of->mutex allocated when opening a sysfs file read-only
(which overlayfs might do) is confused with of->mutex of a file opened
writable (held in write to sysfs file, which overlayfs won't do).
Assigning them separate lockdep classes fixes that bunch and it's
obviously safe"
