Re: [Crash-utility] [PATCH 1/3] defs.h: Fix the value of TIF_SIGPENDING macro
-----Original Message-----
Use the "grep" command to view the value of the
TIF_SIGPENDING
macro in the kernel source code, and modify the wrong value in
the defs.h file.
Thank you for the report, good catch!
Those are not wrong values, just have not been updated to the current values..
For example, with regard to mips (including mips64?), it was changed at v2.6.23:
$ git grep '^#define TIF_SIGPENDING' v2.6.22:include/asm-mips
v2.6.22:include/asm-mips:thread_info.h:#define TIF_SIGPENDING 2 /* signal
pending */
$ git grep '^#define TIF_SIGPENDING' v2.6.23:include/asm-mips
v2.6.23:include/asm-mips:thread_info.h:#define TIF_SIGPENDING 1 /* signal
pending */
As far as I've checked, those were changed respectively:
ARM 2 -> 0 at v2.6.23
MIPS 2 -> 1 at v2.6.23
MIPS64 2 -> 1 at v2.6.23
PPC 2 -> 1 at v2.6.23
IA64 1 -> 0 at v2.6.23
PPC64 2 -> 1 at v2.6.23
S390 2 -> 1 at v3.16
S390X 2 -> 1 at v3.16
So how about something like this?
#define TIF_SIGPENDING (THIS_KERNEL_VERSION >= LINUX(2,6,23) ? 0 : 2)
Thanks,
