From: Kay Sievers <kay.sievers@xxxxxxxx> Subject: vfs: get_sb_single() - do not pass options twice Filesystem code usually destroys the option buffer while parsing it, which leads to errors when the same buffer is passed twice. In case we fill a new superblock with the options, do not pass the options again to the remount() call.
