Subject: [PATCH 1/1] copy: add OCFS2 reflink support
|
||||
|
||||
* src/copy.c (copy_reg): When cp is invoked with '--reflink=[WHEN]', try
|
||||
OCFS2 reflink file first, if it fails, try btrfs clone file later if
|
||||
possible. The reflink will fail with EEXIST if the destination file
|
||||
already exists on OCFS2, in this case, it means the user intended to
|
||||
do OCFS2 reflink rather than btrfs clone, so we need not try the latter.
