From 0d72b92883c651a11059d93335f33d65c6eb653b Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 7 Aug 2023 15:38:33 -0400 Subject: fs: pass the request_mask to generic_fillattr generic_fillattr just fills in the entire stat struct indiscriminately today, copying data from the inode. There is at least one attribute (STATX_CHANGE_COOKIE) that can have side effects when it is reported, and we're looking at adding more with the addition of multigrain timestamps. Add a request_mask argument to generic_fillattr and have most callers just pass in the value that is passed to getattr. Have other callers (e.g. ksmbd) just pass in STATX_BASIC_STATS. Also move the setting of STATX_CHANGE_COOKIE into generic_fillattr.
