From a30eec2a8650a77f754e84b2e15f062fe652baa7 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Sun, 16 May 2010 03:00:00 -0400 Subject: [PATCH] ext4: stop issuing discards if not supported by device Turn off issuance of discard requests if the device does not support it - similar to the action we take for barriers. This will save a little computation time if a non-discardable device is mounted with -o discard, and also makes it obvious that it's not doing what was asked at mount time ...
