Subject: [Cluster-devel] [PATCH] use CURRENT_TIME_SEC instead of get_seconds in gfs2
Date: Thu, 18 Jan 2007 16:41:23 -0600 [thread overview]
Message-ID: <45AFF793.6090903@redhat.com> (raw)
I was looking something else up and came across this...
I don't honestly have a good reason to change it other than to make it
like every other Linux filesystem in this regard. ;-) It doesn't
functionally change anything, but makes some lines shorter. :)
I'm also curious; why does gfs2 have 64-bits of on-disk timestamps, but
not in timespec_t format, and only stores second resolutions? Seems like
you're halfway to sub-second resolutions already.
I suppose if that gets implemented then all of the below should
instead be CURRENT_TIME not CURRENT_TIME_SEC.
Thanks,
-Eric

Assign inode i_ctime to CURRENT_TIME_SEC rather than reaching
into tv_sec and using get_seconds.
