  useful constants: struct qstr for ".." (2021-04-15 22:36:45 -0400)

----------------------------------------------------------------
Al Viro (7):
      constify dentry argument of dentry_path()/dentry_path_raw()
      get rid of autofs_getpath()
      apparmor:match_mn() - constify devpath argument
      autofs: should_expire() argument is guaranteed to be positive
      whack-a-mole: kill strlen_user() (again)
      hostfs_open(): don't open-code file_dentry()
      useful constants: struct qstr for ".."

Mikulas Patocka (1):
      buffer: a small optimization in grow_buffers
