Subject: [GIT PULL] vfs netfs

Hey Linus,

A pidfs patch ended up in the branch and I didn't notice it. I decided
to leave it in here instead of rebasing the whole branch.

/* Summary */

This contains various fixes for the netfs library and related
filesystems and infrastructure:

afs:

    - Fix missing wire-up of afs_retry_request().

    - Fix the setting of the server responding flag in afs.

    - Fix possible infinite loop with unresponsive servers.

    - Remove unused struct and function prototype.

cachefiles:

    - Fix a dentry leak in cachefiles_open_file().

    - Fix incorrect length return value in cachefiles_ondemand_fd_write_iter().

    - Fix missing pos updates in cachefiles_ondemand_fd_write_iter().

    - Clean up in cachefiles_commit_tmpfile().

    - Fix NULL pointer dereference in object->file.

    - Add a memory barrier for FSCACHE_VOLUME_CREATING.

netfs:

    - Advance iterator correctly rather than jumping it.

    - Add folio_queue API documentation.

    - Fix the netfs_folio tracepoint to handle NULL mapping.

    - Remove call to folio_index().

    - Fix a few minor bugs in netfs_page_mkwrite().

    - Remove unnecessary references to pages.

pidfs:

    - Check for valid pid namespace.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)

All patches are based on v6.12-rc1 and have been sitting in linux-next.
