From 9fd097b14918875bd6f125ed699d7bbbba5893ee Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 21 Apr 2011 21:32:55 +0200 Subject: block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers In-kernel disk event polling doesn't matter for legacy/fringe drivers and may lead to infinite event loop if ->check_events() implementation generates events on level condition instead of edge. Now that block layer supports suppressing exporting unlisted events, simply leaving disk->events cleared allows these drivers to keep the internal revalidation behavior intact while avoiding weird interactions with userland event handler.
