* dm: adjust structure members to improve alignmentMike Snitzer2018-06-081-1/+1
| | | | | | | | | Eliminate most holes in DM data structures that were modified by commit 6f1c819c21 ("dm: convert to bioset_init()/mempool_init()"). Also prevent structure members from unnecessarily spanning cache lines. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
* dm: Use kzalloc for all structs with embedded biosets/mempoolsKent Overstreet2018-06-051-1/+1
| | | | | | | | | | | | 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.)

* dm bio prison: use rb_entry() rather than container_of()Geliang Tang2017-06-191-1/+1
| | | | | | | | | To make the code clearer, use rb_entry() instead of container_of() to deal with rbtree. Signed-off-by: Geliang Tang <geliangtang@gmail.com> Acked-by: Coly Li <colyli@suse.de> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
* dm bio prison v2: new interface for the bio prisonJoe Thornber2017-03-071-0/+369
The deferred set is gone and all methods have _v2 appended to the end of their names to allow for continued use of the original bio prison in DM thin-provisioning. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
