UBI already checks that @min io size is the power of 2 at io_init.
It is save to use bit operations then.

UBI: use separate mutex for volumes checking2007-12-26T17:15:17ZArtem Bityutskiy2007-12-25T16:13:33Zurn:sha1:783b273afab43437dca731a229d53d72faf77fd3
Introduce a separate mutex which serializes volumes checking,
because we cammot really use volumes_mutex - it cases reverse
locking problems with mtd_tbl_mutex when gluebi is used -
thanks to lockdep.

UBI: add UBI devices reference counting2007-12-26T17:15:17ZArtem Bityutskiy2007-12-17T15:37:26Zurn:sha1:e73f4459d969bb266f03dd4cbe21bdba8cb2732c
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.

UBI: introduce volume refcounting2007-12-26T17:15:16ZArtem Bityutskiy2007-12-17T13:42:57Zurn:sha1:d05c77a816974c09f8c7e8f48e5b9f7b59dafdf3
Add ref_count field to UBI volumes and remove weired "vol->removed"
field. This way things are better understandable and we do not have
to do whold show_attr operation under spinlock.

UBI: fix and cleanup volume opening functions2007-12-26T17:15:15ZArtem Bityutskiy2007-12-17T12:22:55Zurn:sha1:35ad5fb76cc0a08e14068408b064103439feee36
This patch fixes error codes of the functions - if the device number
is out of range, -EINVAL should be returned. It also removes unneeded
try_module_get call from the open by name function.

UBI: get device when opening volume2007-12-26T17:15:15ZArtem Bityutskiy2007-12-17T11:09:09Zurn:sha1:450f872a8e1763c883c9f723e6937b7ed223e6d3
When a volume is opened, get its kref via get_device() call.
And put the reference when closing the volume. With this, we
may have a bit saner volume delete.

Transform vtbl_mutex to volumes_mutex - this just makes code
easier to understand.
