Subject: Re: [PATCH RFC v2 07/18] fs: maintain a global device-to-superblock table
Date: Wed, 24 Jun 2026 16:05:59 +0200 [thread overview]
Message-ID: <20260624140559.GB7692@lst.de> (raw)
In-Reply-To: <20260616-work-super-bdev_holder_global-v2-7-7df6b864028e@kernel.org>
FYI, I still think maintaining a dev_t to sb mapping vs having a holder
register a claim is a major step backwards architecturally. I spent
a lot of effort to get us out of this.
