Subject: Merge tag 'vfs-6.10.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=103fb219cf57fc3641d92af2f4f438080cea3efc;p=linux.git

Merge tag 'vfs-6.10.mount' of git://git./linux/kernel/git/vfs/vfs

Pull vfs mount API conversions from Christian Brauner:
 "This converts qnx6, minix, debugfs, tracefs, freevxfs, and openpromfs
  to the new mount api, further reducing the number of filesystems
  relying on the legacy mount api"

* tag 'vfs-6.10.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  minix: convert minix to use the new mount api
  vfs: Convert tracefs to use the new mount API
  vfs: Convert debugfs to use the new mount API
  openpromfs: finish conversion to the new mount API
  freevxfs: Convert freevxfs to the new mount API.
  qnx6: convert qnx6 to use the new mount api
