[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. Signed-off-by: J.
