      [PATCH] Avoid console spam with ext3 aborted journal. · 30121624
      Stephen Tweedie authored
      Avoid console spam with ext3 aborted journal.
      
      ext3 usually reports error conditions that it detects in its environment.
      But when its journal gets aborted due to such errors, it can sometimes
      continue to report that condition forever, spamming the console to such
      an extent that the initial first cause of the journal abort can be lost.
      
      When the journal aborts, we put the filesystem into readonly mode.  Most
      subsequent filesystem operations will get rejected immediately by checks
      for MS_RDONLY either in the filesystem or in the VFS.  But some paths do
      not have such checks --- for example, if we continue to write to a file
      handle that was opened before the fs went readonly.  (We only check for
      the ROFS condition when the file is first opened.)  In these cases, we
      can continue to generate log errors similar to
      
      EXT3-fs error (device $DEV) in start_transaction: Journal has aborted
      
      for each subsequent write.
      
      There is really no point in generating these errors after the initial
      error has been fully reported.  Specifically, if we're starting a
      completely new filesystem operation, and the filesystem is *already*
      readonly (ie. the ext3 layer has already detected and handled the
      underlying jbd abort), and we see an EROFS error, then there is simply
      no point in reporting it again.

      [PATCH] Fix filp being passed through raw ioctl handler · e72022e1
      Stephen Tweedie authored
      Don't pass meaningless file handles to block device ioctls.
      
      The recent raw IO ioctl-passthrough fix started passing the raw file
      handle into the block device ioctl handler.  That's unlikely to be
      useful, as the file handle is actually open on a character-mode raw
      device, not a block device, so dereferencing it is not going to yield
      useful results to a block device ioctl handler.
      
      Previously we just passed NULL; also not a value that can usefully
      be dereferenced, but at least if it does happen, we'll oops instead of
      silently pretending that the file is a block device, so NULL is the more
      defensive option here.  This patch reverts to that behaviour.
      
      Noticed by Al Viro.
