Subject: Re: [PATCH RFC 14/41] debugfs: use fc_init_pseudo()
Date: Tue, 10 Nov 2026 09:24:15 +0000 [thread overview]
Message-ID: <sashiko-outbox-206728@kernel.org> (raw)
In-Reply-To: <20261110-work-loop-pseudo-v1-14-4c998976c6c7@kernel.org>
> Initialize debugfs as a pseudo filesystem. This raises SB_I_PSEUDO and
> also SB_I_NOEXEC and SB_I_NODEV. debugfs never holds executables or
> device nodes.
>
> SB_I_NOEXEC also refuses PROT_EXEC mappings. The debugfs files that
> can be mapped, kcov, relay channels and powernv's memtrace, map data.
