Subject: [PATCH v2 5/6] libfs: set FMODE_NOWAIT on dir open
Date: Wed, 10 May 2023 19:52:53 +0900 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
the readdir can technically wait a bit on a spinlock, but that should
never wait for long enough to return EAGAIN -- just set the capability
flag on directories f_mode
