Description
Feature or enhancement
fcntl
exposes many constants for the fcntl
and ioctl
system calls. The module should expose FICLONE
and FICLONERANGE
too; they can be passed to ioctl
to share some data of one file with another file by reflinking on some filesystems (e.g., btrfs, OCFS2, and XFS).
https://man7.org/linux/man-pages/man2/ioctl_ficlone.2.html
Pitch
These constants can be used to reflink files in users' code, and they have a potential to be used in shutil
in the future #81338.
