From d377535405686f735b90a8ad4ba269484cd7c96e Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Tue, 5 Jun 2018 05:26:33 -0400 Subject: dm: Use kzalloc for all structs with embedded biosets/mempools mempool_init()/bioset_init() require that the mempools/biosets be zeroed first; they probably should not _require_ this, but not allocating those structs with kzalloc is a fairly nonsensical thing to do (calling mempool_exit()/bioset_exit() on an uninitialized mempool/bioset is legal and safe, but only works if said memory was zeroed.)
