From 1cd66c93ba8cdb873258f58ae6a817b28a02bcc3 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 27 Sep 2016 11:03:58 +0200 Subject: fs: make remaining filesystems use .rename2 This is trivial to do: - add flags argument to foo_rename() - check if flags is zero - assign foo_rename() to .rename2 instead of .rename This doesn't mean it's impossible to support RENAME_NOREPLACE for these filesystems, but it is not trivial, like for local filesystems. RENAME_NOREPLACE must guarantee atomicity (i.e. it shouldn't be possible for a file to be created on one host while it is overwritten by rename on another host). Filesystems converted: 9p, afs, ceph, coda, ecryptfs, kernfs, lustre, ncpfs, nfs, ocfs2, orangefs. After this, we can get rid of the duplicate interfaces for rename.
