Subject: Re: [PATCH v6 1/7] fs: pass the request_mask to generic_fillattr
Jeff Layton <jlayton@...nel.org> writes:
> 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.
