      CRED: Fix RCU warning due to previous patch fixing __task_cred()'s checks · 694f690d
      David Howells authored
      Commit 8f92054e ("CRED: Fix __task_cred()'s lockdep check and banner
      comment") fixed the lockdep checks on __task_cred().  This has shown up
      a place in the signalling code where a lock should be held - namely that
      check_kill_permission() requires its callers to hold the RCU lock.
      
      Fix group_send_sig_info() to get the RCU read lock around its call to
      check_kill_permission().
      
      Without this patch, the following warning can occur:

      block_dev: always serialize exclusive open attempts · e75aa858
      Tejun Heo authored
      bd_prepare_to_claim() incorrectly allowed multiple attempts for
      exclusive open to progress in parallel if the attempting holders are
      identical.  This triggered BUG_ON() as reported in the following bug.
      
        https://bugzilla.kernel.org/show_bug.cgi?id=16393
      
      __bd_abort_claiming() is used to finish claiming blocks and doesn't
      work if multiple openers are inside a claiming block.  Allowing
      multiple parallel open attempts to continue doesn't gain anything as
      those are serialized down in the call chain anyway.  Fix it by always
      allowing only single open attempt in a claiming block.
      
      This problem can easily be reproduced by adding a delay after
      bd_prepare_to_claim() and attempting to mount two partitions of a
      disk.

      parisc: pass through '\t' to early (iodc) console · d9b68e5e
      Kyle McMartin authored
      The firmware handles '\t' internally, so stop trying to emulate it
      (which, incidentally, had a bug in it.)
      
      Fixes a really weird hang at bootup in rcu_bootup_announce, which,
      as far as I can tell, is the first printk in the core kernel to use
      a tab as the first character.
