The mutex essencially protects the entire UBI device, so the old @volumes_mutex name is a little misleading. Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

The @mult_mutex does not serve any purpose. We already have @volumes_mutex and it is enough. The @volume mutex is pushed down to the 'ubi_rename_volumes()', because we want first to open all volumes in the exclusive mode, and then lock the mutex, just like all other ioctl's (remove, re-size, etc) do.

Introduce a new ioctl UBI_IOCSETPROP to set properties on a volume. Also add the first property: UBI_PROP_DIRECT_WRITE, this property is used to set the ability to use direct writes in userspace Signed-off-by: NSidney Amani <seed@uffs.org> Signed-off-by: NCorentin Chary <corentincj@iksaif.net> Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

UBI ioctl's do not work when running 64-bit kernel and 32-bit user-land. Fix this by adding the compat_ioctl method. Also, UBI serializes all ioctls, so more than one ioctl at a time is not a problem. Amd UBI does not seem to depend on anything else, so use unlocked_ioctl instead of ioctl (no BKL needed).

Some ioctl's in UBI are enabled only when debugging is switched on. There is not particular reason for this, just noone needed them. However, some people need the now for their user-space development. Thus, allow these ioctl's even if UBI debugging is disabled. Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

This is one more step on the way to "removable" UBI devices. It adds reference counting for UBI devices. Every time a volume on this device is opened - the device's refcount is increased. It is also increased if someone is reading any sysfs file of this UBI device or of one of its volumes. Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

This patch is a preparation to make UBI devices dynamic. It adds an UBI control device which has dynamically allocated major number and registers itself as "ubi_ctrl". It does not do anything so far. The idea is that this device will allow to attach/detach MTD devices from userspace. This is symilar to what the Linux device mapper has. The next things to do are: * Fix UBI, because it now assumes UBI devices cannot go away * Implement control device ioctls which will attach/detach MTD devices Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>
