Subject: [PATCH 2/3] export: add EACCES to the list of known path_lookup_error() errors.
Date: Wed, 11 Oct 2023 15:58:01 +1100 [thread overview]
Message-ID: <20231011051131.24667-3-neilb@suse.de> (raw)
In-Reply-To: <20231011051131.24667-1-neilb@suse.de>
If a 'stat' results in EACCES (for root), then it is likely a permanent
problem. One possible cause is a 'fuser' filesystem which only gives
any access to the user which mounted it.
So it is reasonable for EACCES to be a "path lookup error"
