      mm + fs: store shadow entries in page cache · 91b0abe3
      Johannes Weiner 提交于
      Reclaim will be leaving shadow entries in the page cache radix tree upon
      evicting the real page.  As those pages are found from the LRU, an
      iput() can lead to the inode being freed concurrently.  At this point,
      reclaim must no longer install shadow pages because the inode freeing
      code needs to ensure the page tree is really empty.
      
      Add an address_space flag, AS_EXITING, that the inode freeing code sets
      under the tree lock before doing the final truncate.  Reclaim will check
      for this flag before installing shadow pages.

      mm: filemap: move radix tree hole searching here · e7b563bb
      Johannes Weiner 提交于
      The radix tree hole searching code is only used for page cache, for
      example the readahead code trying to get a a picture of the area
      surrounding a fault.
      
      It sufficed to rely on the radix tree definition of holes, which is
      "empty tree slot".  But this is about to change, though, as shadow page
      descriptors will be stored in the page cache after the actual pages get
      evicted from memory.
      
      Move the functions over to mm/filemap.c and make them native page cache
      operations, where they can later be adapted to handle the new definition
      of "page cache hole".

      fs: push sync_filesystem() down to the file system's remount_fs() · 02b9984d
      Theodore Ts'o 提交于
      Previously, the no-op "mount -o mount /dev/xxx" operation when the
      file system is already mounted read-write causes an implied,
      unconditional syncfs().  This seems pretty stupid, and it's certainly
      documented or guaraunteed to do this, nor is it particularly useful,
      except in the case where the file system was mounted rw and is getting
      remounted read-only.
      
      However, it's possible that there might be some file systems that are
      actually depending on this behavior.  In most file systems, it's
      probably fine to only call sync_filesystem() when transitioning from
      read-write to read-only, and there are some file systems where this is
      not needed at all (for example, for a pseudo-filesystem or something
      like romfs).
