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. --=20 You are receiving this mail because: You are the assignee for the bug.=
