In coreutils this feature may be used with {{{cp --reflink file1 file2}}} Syntax is: {{{ioctl(dest_desc, BTRFS_IOC_CLONE, src_desc)}}}, where dest_desc and src_desc are file descriptors. It would be nice to utilize this feature in MC, for example, as ""Copy-on-write"" switch in copy file dialog (appearing when source and destination is on one Btrfs filesystem) or as a separate operation in UI.",enhancement,closed,minor,4.8.22,mc-vfs,master,fixed,,deletesoftware@… wolf+mc@…,,,merged,committed-master
