[GIT PULL 12/12 for v7.1] vfs misc

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */

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
