[PATCH] knfsd: nfsd4: rename state list fields
Trivial renaming patch:
I can never remember, while looking at various lists relating the nfsd4 state
structures, which are the "heads" and which are items on other lists, or which
structures are actually on the various lists. The following convention helps
me: given structures foo and bar, with foo containing the head of a list of
bars, use "bars" for the name of the head of the list contained in the struct
foo, and use "per_foo" for the entries in the struct bars.
Already done for struct nfs4_file; go ahead and do it for the other nfsd4
state structures.
