Merge tag 'vfs-6.19-rc1.fs_header' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull fs header updates from Christian Brauner:
 "This contains initial work to start splitting up fs.h.

  Begin the long-overdue work of splitting up the monolithic fs.h
  header. The header has grown to over 3000 lines and includes types and
  functions for many different subsystems, making it difficult to
  navigate and causing excessive compilation dependencies.

  This series introduces new focused headers for superblock-related
  code:

   - Rename fs_types.h to fs_dirent.h to better reflect its actual
     content (directory entry types)

   - Add fs/super_types.h containing superblock type definitions

   - Add fs/super.h containing superblock function declarations

  This is the first step in a longer effort to modularize the VFS
  headers.

  Cleanups:

   - Inode Field Layout Optimization (Mateusz Guzik)

     Move inode fields used during fast path lookup closer together to
     improve cache locality during path resolution.

   - current_umask() Optimization (Mateusz Guzik)

     Inline current_umask() and move it to fs_struct.h. This improves
     performance by avoiding function call overhead for this
     frequently-used function, and places it in a more appropriate
     header since it operates on fs_struct"

* tag 'vfs-6.19-rc1.fs_header' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  fs: move inode fields used during fast path lookup closer together
  fs: inline current_umask() and move it to fs_struct.h
  fs: add fs/super.h header
  fs: add fs/super_types.h header
  fs: rename fs_types.h to fs_dirent.h
