      kallsyms: make KSYM_NAME_LEN include space for trailing '\0' · 9281acea
      由 Tejun Heo 提交于 
      KSYM_NAME_LEN is peculiar in that it does not include the space for the
trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating
buffer.  This is nonsense and error-prone.  Moreover, when the caller
forgets that it's very likely to subtly bite back by corrupting the stack
because the last position of the buffer is always cleared to zero.

This patch increments KSYM_NAME_LEN by one and updates code accordingly.

* off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro
  is fixed.

* Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together,
  MODULE_NAME_LEN was treated as if it didn't include space for the
  trailing '\0'.  Fix it.

      Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM · edd5cd4a
      由 David Woodhouse 提交于 
      Not all the world is an i386.  Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer.  Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.

Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely.  In fact, ARM already had that, but called it
sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
the needed compatibility routine.  And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.

Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

      update checkpatch.pl to version 0.06 · d8aaf121
      由 Andy Whitcroft 提交于 
      Update to checkpatch.pl v0.06.  Of note:

 - do { and else handled correctly as control structures for { matching
 - trailing whitespace correctly tripped when line otherwise empty
 - support for const, including const foo * const bar
 - multiline macros defining values correctly reported

This version of checkpatch.pl can be found at the following URL:

http://www.kernel.org/pub/linux/kernel/people/apw/checkpatch/checkpatch.pl-0.06

Full Changelog:

Andy Whitcroft (14):
      Version: 0.06
      cleanup the Type regular expression declarations
      fix up block counting
      end of line counts as a space for ++ and --
      do { needs the same checks as if, for et al
      handle "const foo * const a" as a valid type
      add spacing checks following ;
      complete whitespace lines should trip trailing whitespace check
      else is also a block control structure
      badly formatted else can trip function declaration
      detect and report trailing statements after else
      types need to be terminated by a boundary
      multiline macros defining values should be surrounded by parentheses
      soften the wording of the Signed-off-by: warnings
