Subject: [PATCH 5/5] uapi: fix another asm/shmbuf.h userspace compilation
error
Date: Sat, 25 Feb 2017 12:34:56 +0000
Replace size_t with __kernel_size_t to fix asm/shmbuf.h userspace
compilation errors like this:
/usr/include/asm-generic/shmbuf.h:28:2: error: unknown type name 'size_t'
size_t shm_segsz; /* size of segment (bytes) */
x32 is the only architecture where sizeof(size_t) is less than
sizeof(__kernel_size_t), but as the kernel treats shm_segsz field as
__kernel_size_t anyway, UAPI should follow. Thanks to little-endiannes
of x32 and 64-bit alignment of the field following shm_segsz, this
change doesn't break ABI, and the difference doesn't manifest itself
easily.
