[PATCH] workqueue, freezer: unify spelling of 'freeze' + 'able' to'freezable'

From: Tejun Heo
Date: Wed Feb 16 2011 - 03:34:54 EST


There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'. The former is the more prominent one. The latter is
mostly used by workqueue and in a few other odd places. Unify the
spelling to 'freezable'.

I'd like to push this through wq#fixes-2.6.38 branch as routing this
type of changes through linux-next usually only increases the amount
of conflicts. Rafael, can you please ack if you agree?

Thanks.
