The 2.6.25 ptrace_bts_config structure in asm-x86/ptrace-abi.h
is defined with u32 types:
#include <asm/types.h>
/* configuration/status structure used in PTRACE_BTS_CONFIG and
PTRACE_BTS_STATUS commands.
*/
struct ptrace_bts_config {
/* requested or actual size of BTS buffer in bytes */
u32 size;
/* bitmask of below flags */
u32 flags;
/* buffer overflow signal */
u32 signal;
/* actual size of bts_struct in bytes */
u32 bts_size;
};
#endif
But u32 is only accessible in asm-x86/types.h if __KERNEL__,
leading to compile errors when ptrace.h is included from
user-space. The double-underscore versions that are exported
to user-space in asm-x86/types.h should be used instead.
