linuxkpi/sysfs.h: Cast arg2 through intptr_t to avoid GCC warning
The code compiles fine under Clang, but GCC on PPC is less permissive
about
integer and pointer sizes. (An intmax_t is clearly *large enough* to
hold a
pointer value.)
Another follow-up to r290475.
This shouldn't compile either.
Hi Conrad,
static int
-sysctl_root_handler_locked(struct sysctl_oid *oid, void *arg1, intptr_t arg2,
+sysctl_root_handler_locked(struct sysctl_oid *oid, void *arg1, intmax_t arg2,
struct sysctl_req *req, struct rm_priotracker *tracker)
Given that the second argument is sometimes used for pointers, maybe we
should keep it intptr_t. Or add a compile time assert that
sizeof(intmax) >= sizeof(intptr_t) which I think doesn't hold?
