From: "jianyun.gao" <jianyungao89@gmail.com>

[ Upstream commit b6c46600bfb28b4be4e9cff7bad4f2cf357e0fb7 ]

Below are some typos in the code comments:

intevals ==> intervals
addesses ==> addresses
unavaliable ==> unavailable
facor ==> factor
droping ==> dropping
exlusive ==> exclusive
decription ==> description
confict ==> conflict
desriptions ==> descriptions
otherwize ==> otherwise
vlaue ==> value
cheching ==> checking
exisitng ==> existing
modifed ==> modified
differenciate ==> differentiate
refernece ==> reference
permissons ==> permissions
indepdenent ==> independent
spliting ==> splitting

Just fix it.
