From 00e9ffcd27cc5d0af9076383c6242c32335546f8 Mon Sep 17 00:00:00 2001 From: Andreas Rohner Date: Thu, 3 Apr 2014 14:50:27 -0700 Subject: nilfs2: add nilfs_sufile_set_suinfo to update segment usage Introduce nilfs_sufile_set_suinfo(), which expects an array of nilfs_suinfo_update structures and updates the segment usage information accordingly. This is basically a helper function for the newly introduced NILFS_IOCTL_SET_SUINFO ioctl.
