From a1706ac4c0201ea0143dc0db0659001b26ceeabb Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 30 May 2011 07:42:51 +0200 Subject: Revert "block: Remove extra discard_alignment from hd_struct." It was not a good idea to start dereferencing disk->queue from the fs sysfs strategy for displaying discard alignment. We ran into first a NULL pointer deref, and after fixing that we sometimes see unvalid disk->queue pointer values. Since discard is the only one of the bunch actually looking into the queue, just revert the change. This reverts commit 23ceb5b7719e9276d4fa72a3ecf94dd396755276.
