There are two 'struct timeval' fields in 'struct rusage'. Unfortunately the definition of timeval is now ambiguous when used in user space with a libc that has a 64-bit time_t, and this also changes the 'rusage' definition in user space in a way that is incompatible with the system call interface. While there is no good solution to avoid all ambiguity here, change the definition in the kernel headers to be compatible with the kernel ABI, using __kernel_old_timeval as an unambiguous base type. In previous discussions, there was also a plan to add a replacement for rusage based on 64-bit timestamps and nanosecond resolution, i.e. 'struct __kernel_timespec'. I have patches for that as well, if anyone thinks we should do that. Reviewed-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> |
