Subject: [PATCH] dm-raid45: API update: Remove dm_put after dm_table_get_md
|
||
|
|
References: bnc#615656
|
||
|
|
Patch-mainline: depends on dm-raid45 being upstream
|
||
|
|
|
||
|
|
Commit ecdb2e257abc33ae6798d3ccba87bdafa40ef6b6, for 2.6.34, removed
|
||
|
|
the dm_get() call from dm_table_get_md(). The dm-raid45 code still has
|
||
|
|
matching dm_put() calls for the dm_table_get_md() calls. This patch removes
|
||
|
|
the dm_put() calls as it's causing too many reference drops and BUG_ONs.
