Ok, thanks for letting us know.
I'll revert the commit (it is only in main
and was basically just cleanup).
I will leave this open for a while, since I
suspect readahead just hides the lockups.
(I'll think about the LORs.)
Basically, readahead means that the read of the
next directory block begins before the buffer lock
is released for the previous block and before the
vnode lock on the directory vnode is unlocked, if
I recall the code correctly.
