[PATCH v4 16/54] convert dlmfs
From: Al Viro <viro@zeniv.linux.org.uk>
Date: 2025-11-18 05:16:10
Also in:
bpf, linux-efi, linux-mm, linux-usb, linuxppc-dev, ocfs2-devel, selinux
Subsystem:
filesystems (vfs and infrastructure), oracle cluster filesystem 2 (ocfs2), the rest · Maintainers:
Alexander Viro, Christian Brauner, Mark Fasheh, Joel Becker, Joseph Qi, Linus Torvalds
All modifications via normal VFS codepaths; just take care of making persistent in ->create() and ->mkdir() and that's it (removal side doesn't need any changes, since it uses simple_rmdir() for ->rmdir() and calls simple_unlink() from ->unlink()).
