Subject: dm table: Constify static struct blk_ksm_ll_ops
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ccde2cbfa31c4d41818a493c1126df05336f8c5a;p=uclinux-h8%2Flinux.git

dm table: Constify static struct blk_ksm_ll_ops

The only usage of dm_ksm_ll_ops is to make a copy of it to the ksm_ll_ops
field in the blk_keyslot_manager struct. Make it const to allow the
compiler to put it in read-only memory.
