Subject: [PATCH 3/3] MTD: remove the 'flags' sysfs file
Date: Tue, 21 Apr 2009 12:32:35 +0300 [thread overview]
Message-ID: <1240306355.19218.5.camel@localhost.localdomain> (raw)
In-Reply-To: <1240306101.19218.2.camel@localhost.localdomain>
It is bad idea to export the MTD flags via sysfs. It is much
cleaner to create a per-flag sysfs file which contains 0 or
1. It is difficult for users to parse '0x400'. We have ioctls
which return the flags, no need to add this to sysfs.
