Subject: [GIT PULL] fuse update for 6.12

Hi Linus,

Please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git
tags/fuse-update-6.12

- Add support for idmapped fuse mounts (Alexander Mikhalitsyn).  This
touches some non-fuse files, these have been reviewed by Christian.

- Add optimization when checking for writeback (yangyun).

- Add tracepoints (Josef Bacik).

- Clean up writeback code (Joanne Koong).

- Clean up request queuing (me).

- Misc fixes.

Thanks,
Miklos
