[PATCH 2/7] fs: support RENAME_NOREPLACE for local filesystems

From: Miklos Szeredi
Date: Tue Aug 23 2016 - 10:12:11 EST

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, ext2, hfs, hfsplus, jffs2, jfs, logfs, minix, msdos, nilfs2,
omfs, reiserfs, sysvfs, ubifs, udf, ufs, vfat.
