[PATCH v3 0/2] kernel.h: container_of() pointer checking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



[Apologies for the resend.  I got both mailing list addresses wrong!]

Patch 2 changes the container_of() macro to improve the compatibility
checking when the member has array type.  As a bonus (?), if the pointer
neither points to a type compatible with the member nor points to a type
compatible with void, compiler errors are produced instead of warnings.

Patch 1 is a prerequisite to avoid a lot of warnings when <linux/bug.h>
is included by <linux/kernel.h>.

1) asm-generic/bug.h: declare struct pt_regs; before function prototype
2) kernel.h: handle pointers to arrays better in container_of()
