Subject: [PATCH 08/13] sysfs: don't ignore options
Date: Wed, 19 Jun 2019 14:30:14 +0200 [thread overview]
Message-ID: <20190619123019.30032-8-mszeredi@redhat.com> (raw)
In-Reply-To: <20190619123019.30032-1-mszeredi@redhat.com>
The options "sync", "async", "dirsync", "lazytime", "nolazytime", "mand"
and "nomand" make no sense for the sysfs filesystem. If these options are
supplied to fsconfig(FSCONFIG_SET_FLAG), then return -EINVAL instead of
silently ignoring the option.
Any implementation, such as mount(8) that needs to parse this option
without failing should simply ignore the return value from fsconfig().
