I find that the mount command for an ext4 filesystem is not accepting the "--nouser_xattr" option, despite that being listed as a valid option in the ext4(5) manpage. This appears to be true in both Fedora 37 and 38. Note that the "--user_xattr" option _is_ accepted. When did this change? I have some external disks shared across multiple systems, and I want to keep them free of user xattrs.

Is this an error in the manpage, or a bug in the mount command itself?

util-linux-core-2.38.1-4.fc38.x86_64
e2fsprogs-1.46.5-4.fc38.x86_64

It was removed from the Linux kernel last September:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/ext4?id=2d544ec923dbe5fbed64a7f43dccf527218380bc

There are some links to discussion in the commit, but the tl;dr is that it’s been deprecated since the 3.5 kernel and someone finally got around to removing it.
