The patch titled Subject: epoll: cleanup: hoist out f_op->poll calls has been removed from the -mm tree. Its filename was epoll-cleanup-hoist-out-f_op-poll-calls.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Eric Wong <normalperson@xxxxxxxx> Subject: epoll: cleanup: hoist out f_op->poll calls This reduces the amount of code inside the ready list iteration loops for better readability IMHO.
