      vfs: __d_path: dont prepend the name of the root dentry · 98dc568b
      Miklos Szeredi 提交于
      In the old times pseudo-filesystems set the name of theroot dentry to
      some prefix like "pipe:" and the name of the child dentry to "[123]"
      and relied on a hack in __d_path() to replace the preceding slash with
      the root's name to get "pipe:[123]".
      
      Then the d_dname() dentry operation was introduced which solved the
      same problem without having to pre-fill the name in each dentry.
      
      Currently the following pseudo filesystems exist in the kernel:
      
      perfmon
      mtd
      anon_inode
      bdev
      pipe
      socket
      
      Of these only perfmon, anon_inode, pipe and socket create
      sub-dentries, all of which have now been switched to using d_dname().
      
      bdev and mtd only create inodes.
      
      This means that now the hack to overwrite the slash can be removed, so
      for unreachable paths (e.g. within a detached mount) the path string
      won't be polluted with garbage.  For these cases a subsequent patch
      will add a prefix, indicating that the path is unreachable.

      ia64: perfmon: add d_dname method · 7ae6bdbd
      Miklos Szeredi 提交于
      Switch ia64/perfmon to using the d_dname() instead of relying on
      __d_path() to prepend the name of the root dentry to the path.

      fs/sysv/super.c: add support for non-PDP11 v7 filesystems · 6d0b5456
      Lubomir Rintel 提交于
      This adds byte order autodetection (of PDP-11 and LE filesystems).  No
      attempt is made to detect big-endian filesystems -- were there any?
      Tested with PDP-11 v7 filesystems and PC-IX maintenance floppy.

      V7: Adjust sanity checks for some volumes · 496ee9b8
      Lubomir Rintel 提交于
      Newly mkfs-ed filesystems from Seventh Edition have last modification
      time set to zero, but are otherwise perfectly valid.
      
      Also, tighten up other sanity checks to filter out most filesystems with
      different bytesex than we're using.
