When abort failed, the driver gets reset handleer called.  In the reset
handler, driver calls 'scsi_done()' callback for same SCSI command packet
(struct scsi_cmnd) multiple times if there are multiple SCSI command packet

in turn, the driver could end up with 'NULL pointer dereference..' during

Also, the patch contains several minor/cosmetic changes besides this.

RPCSEC_GSS: fix leak in krb5 code caused by superfluous kmalloc

I was sloppy when generating a previous patch; I modified the callers of
krb5_make_checksum() to allocate memory for the buffer where the result is
returned, then forgot to modify krb5_make_checksum to stop allocating that
memory itself.  The result is a per-packet memory leak.  This fixes the
problem by removing the now-superfluous kmalloc().

[PATCH] Fix file lookup without ref

There are places in the kernel where we look up files in fd tables and
access the file structure without holding refereces to the file.  So, we
need special care to avoid the race between looking up files in the fd
table and tearing down of the file in another CPU.  Otherwise, one might
see a NULL f_dentry or such torn down version of the file.  This patch
fixes those special places where such a race may happen.

Hirokazu Takata [Wed, 19 Apr 2006 05:21:20 +0000 (22:21 -0700)]
[PATCH] m32r: Fix pt_regs for !COFNIG_ISA_DSP_LEVEL2 target

This modification is required to fix debugging function for m32r targets
with !CONFIG_ISA_DSP_LEVEL2, by unifying 'struct pt_regs' and 'struct
sigcontext' size for all M32R ISA.

Some m32r processor core with !CONFIG_ISA_DSP_LEVEL2 configuration has only
single accumulator a0 (ex.  VDEC2 core, M32102 core, etc.), the others with
CONFIG_ISA_DSP_LEVEL2 has two accumulators, a0 and a1.

This means there are two variations of thread context.  So far, we reduced
and changed stackframe size at a syscall for their context size.  However,
this causes a problem that a GDB for processors with CONFIG_ISA_DSP_LEVEL2
cannot be used for processors with !CONFIG_ISA_DSP_LEVEL2.

From the viewpoint of GDB support, we should reduce such variation of
stackframe size for simplicity.

In this patch, dummy members are added to 'struct pt_regs' and 'struct
sigcontext' to adjust their size for !CONFIG_ISA_DSP_LEVEL2.

This modification is also a one step for a GDB update in future.
Currently, on the m32r, GDB can access process's context by using ptrace
functions in a simple way of register by register access.  By unifying
stackframe size, we have a possibility to make use of ptrace functions of
not only a single register access but also block register access,
PTRACE_{GETREGS,PUTREGS}.

However, for this purpose, we might have to modify stackframe structure
some more; for example, PSW (processor status word) register should be
pre-processed before pushing to stack at a syscall, and so on.  In this
case, we must update carefully both kernel and GDB at a time...
