Merge tag 'vfs-7.1-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
 "Features:
   - coredump: add tracepoint for coredump events
   - fs: hide file and bfile caches behind runtime const machinery

  Fixes:
   - fix architecture-specific compat_ftruncate64 implementations
   - dcache: Limit the minimal number of bucket to two
   - fs/omfs: reject s_sys_blocksize smaller than OMFS_DIR_START
   - fs/mbcache: cancel shrink work before destroying the cache
   - dcache: permit dynamic_dname()s up to NAME_MAX

  Cleanups:
   - remove or unexport unused fs_context infrastructure
   - trivial ->setattr cleanups
   - selftests/filesystems: Assume that TIOCGPTPEER is defined
   - writeback: fix kernel-doc function name mismatch for wb_put_many()
   - autofs: replace manual symlink buffer allocation in autofs_dir_symlink
   - init/initramfs.c: trivial fix: FSM -> Finite-state machine
   - fs: remove stale and duplicate forward declarations
   - readdir: Introduce dirent_size()
   - fs: Replace user_access_{begin/end} by scoped user access
   - kernel: acct: fix duplicate word in comment
   - fs: write a better comment in step_into() concerning .mnt assignment
   - fs: attr: fix comment formatting and spelling issues"
