Subject: Re: [PATCHSET RFC v2 jane 0/5] vfs: enable userspace to reset damaged file storage
Date: Wed, 22 Sep 2021 17:51:44 -0700 [thread overview]
Message-ID: <20210923005144.GA570577@magnolia> (raw)
In-Reply-To: <163192864476.417973.143014658064006895.stgit@magnolia>
I withdraw the patchset due to spiralling complexity and the need to get
back to the other hojillion things.
Dave now suggests creating a RWF_CLEAR_POISON/IOCB_CLEAR_POISON flag to
clear poison ahead of userspace using a regular write to reset the
storage. Honestly I only though of zero writes because I though that
would lead to the least amount of back and forth, which was clearly
wrong.
Jane, could you take over and try that?
