Subject: [PATCH 0/6 v4] nfsd: allocate/free session-based DRC slots on demand
Date: Mon,  9 Dec 2024 09:43:11 +1100	[thread overview]
Message-ID: <20241208224629.697448-1-neilb@suse.de> (raw)

Changes from v3 include:
 - use GFP_NOWAIT more consistently - don't use GFP_ATOMIC
 - document reduce_session_slots()
 - change sl_generation to u16.  As we reduce the number of slots one at
   a time and update se_slot_gen each time, we could cycle a u8 generation
   counter quickly.

Thanks,
NeilBrown
