From f03b8ad8d38634d13e802165cc15917481b47835 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 27 Sep 2016 11:03:57 +0200 Subject: fs: support RENAME_NOREPLACE for local filesystems This is trivial to do: - add flags argument to foo_rename() - check if flags doesn't have any other than RENAME_NOREPLACE - assign foo_rename() to .rename2 instead of .rename Filesystems converted: affs, bfs, exofs, ext2, hfs, hfsplus, jffs2, jfs, logfs, minix, msdos, nilfs2, omfs, reiserfs, sysvfs, ubifs, udf, ufs, vfat.

There is no plan to transistion CURRENT_TIME_SEC to use y2038 safe time interfaces. current_time() will also be extended to use superblock range checking parameters when range checking is introduced. This works because alloc_super() fills in the the s_time_gran in super block to NSEC_PER_SEC.
