In the Linux kernel, the following vulnerability has been resolved:
debugfs: Fix lockdown check for mmap_prepare
Commit 651fdda8406d ("relay: update relay to use mmap_prepare")
changed the mmap file operation to mmap_prepare for relayfs, but
the lockdown check in debugfs was not updated accordingly.
This prevents debugfs from being locked down when the kernel is in
integrity mode if a file uses mmap_prepare but not mmap.
Since the conversion to mmap_prepare across the kernel is not yet
complete, update the lockdown check to look for both mmap and
mmap_prepare to ensure comprehensive coverage.

In the Linux kernel, the following vulnerability has been resolved: debugfs: Fix lockdown check for mmap_prepare Commit 651fdda8406d ("relay: update relay to use mmap_prepare") changed the `mmap` file operation to `mmap_prepare` for relayfs, but the lockdown check in debugfs was not updated accordingly. This prevents debugfs from being locked down when the kernel is in integrity mode if a file uses `mmap_prepare` but not `mmap`. Since the conversion to `mmap_prepare` across the kernel is not yet complete, update the lockdown check to look for both `mmap` and `mmap_prepare` to ensure comprehensive coverage.
