Merge tag 'configfs-for-linus' of git://git.infradead.org/users/hch/configfs
Pull configfs updates from Christoph Hellwig: - A large patch from me to simplify setting up the list of default groups by actually implementing it as a list instead of an array. - a small Y2083 prep patch from Deepa Dinamani. Probably doesn't matter on it's own, but it seems like he is trying to get rid of all CURRENT_TIME uses in file systems, which is a worthwhile goal. * tag 'configfs-for-linus' of git://git.infradead.org/users/hch/configfs: configfs: switch ->default groups to a linked list configfs: Replace CURRENT_TIME by current_fs_time()
