Changes from v2: lkml.kernel.org/r/20180601160125.30031-1-dave@xxxxxxxxxxxx - Dropped original patch 1 (which removed the EINVAL returns for WARN_ON) as well as patch 5. - Added a new patch 1, which simplifies the alloc after mhocko's changes (originally suggested by Linus). - Use max_t instead of min_t for the resize. Changes from v1 lkml.kernel.org/r/20180524211135.27760-1-dave@xxxxxxxxxxxx - patch 2 is reworked a bit based on the commments from Herbert Xu. o upon failure, retry immediately with GFP_NOFAIL (simpler) o the caller now passes the needed semantics, not bucket_table_alloc(). o we consider min_size when resizing, not just HASH_MIN_SIZE. - removed patch 3; not need after Michal's patch. Hi, This series is the result of the discussion with Linus around ipc subsystem initialization and how it behaves with error return when calling rhashtable_init()[1]. Instead of caring about the error or calling the infamous BUG_ON, Linus suggested we guarantee the rhashtable allocation. First two patches deal with the rhashtable_init() changes, while the patches 3+4 remove some ipc hacks we no longer need. Please consider for v4.19. [0] https://lkml.org/lkml/2018/5/23/758 Thanks!
