[PATCH v2 3/6] staging: lustre: llite: remove unused parameters from md_{get,set}xattr()

From: James Simmons
Date: Tue May 29 2018 - 10:22:03 EST


From: "John L. Hammond" <john.hammond@xxxxxxxxx>

md_getxattr() and md_setxattr() each have several unused
parameters. Remove them and improve the naming or remaining
parameters.
