Subject: nfsd4: nfsd4_lock() cleanup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e1aaa8916f19d23d39d88e985bc6933a74159e91;p=linux-beck.git

nfsd4: nfsd4_lock() cleanup

Share a little common logic.  And note the comments here are a little
out of date (e.g. we don't always create new state in the "new" case any
more.)
