fix similar typos to successfull

2009-01-08T16:31:15+00:00

When I review ocfs2 code, find there are 2 typos to "successfull".  After
doing grep "successfull " in kernel tree, 22 typos found totally -- great
minds always think alike :)

This patch fixes all the similar typos. Thanks for Randy's ack and comments.

UBI: avoid unnecessary division operations

2008-07-24T10:32:54+00:00

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 checking

2007-12-26T17:15:17+00:00

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 counting

2007-12-26T17:15:17+00:00

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 refcounting

2007-12-26T17:15:16+00:00

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 functions

2007-12-26T17:15:15+00:00

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 volume

2007-12-26T17:15:15+00:00

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.
