Subject: [PATCH 0/2] lockref tidy ups + touch ups to it's usage by dcache
Date: Fri, 24 Jul 2026 19:14:20 +0200 [thread overview]
Message-ID: <20260724171422.429284-1-mjguzik@gmail.com> (raw)
The open-coded check for < 0 indicating a dead object uses information
it should not know, so to speak.
This is a preliminary clean up for a longer term goal of moving dcache
away from lockref into an approach which can atomic_add both ways
instead of suffering the cmpxchg loop.

lockref: tidy up dead count handling
dcache: use lockref routines for dead count checks
