[dm-devel] [PATCH 05/11] dm-zoned: don't set the discard_alignment queue limit

[Christoph Hellwig]

The discard_alignment queue limit is named a bit misleading means the
offset into the block device at which the discard granularity starts.
Setting it to the discard granularity as done by dm-zoned is mostly
harmless but also useless.
