Subject: [PATCH] fuse: cache POSIX ACLs when setting them
Date: Wed, 1 Jul 2026 12:00:52 +0100 [thread overview]
Message-ID: <20260701110052.5309-1-luis@igalia.com> (raw)
When setting an ACL in an inode we can immediately add it to the cache.
This is a small optimisation, as currently an ACL is only added to the
cache when reading it again, which involves an extra GETXATTR hop into
user-space.
