Even after adding such an entry to btrfs_show_options(), the following occurs, # mount -o nologreplay,ro /dev/loop6 /mnt/ # mount | grep loop6 /dev/loop6 on /mnt type btrfs (ro,relatime,seclabel,nologreplay,space_cache,subvolid=5,subvol=/) # mount -o remount,rw /dev/loop6 /mnt/ # mount | grep loop6 /dev/loop6 on /mnt type btrfs (rw,relatime,seclabel,nologreplay,space_cache,subvolid=5,subvol=/) As can be seen from the last line, both 'rw' and 'nologreplay' options are set. -- chandan -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
