Subject: [PATCH] include/uapi/linux/swab: Fix potentially missing
|
||
__always_inline

Commit bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining
|
||
of some byteswap operations") added __always_inline to swab functions
|
||
and commit 283d75737837 ("uapi/linux/stddef.h: Provide __always_inline to
|
||
userspace headers") added a definition of __always_inline for use in
|
||
exported headers when the kernel's compiler.h is not available.
|
||
|
||
However, since swab.h does not include stddef.h, if the header soup does
|
||
not indirectly include it, the definition of __always_inline is missing,
|
||
resulting in a compilation failure, which was observed compiling the
|
||
perf tool using exported headers containing this commit:
|
||
|
||
In file included from /usr/include/linux/byteorder/little_endian.h:12:0,
|
||
from /usr/include/asm/byteorder.h:14,
|
||
from tools/include/uapi/linux/perf_event.h:20,
|
||
from perf.h:8,
|
||
from builtin-bench.c:18:
|
||
/usr/include/linux/swab.h:160:8: error: unknown type name ‘__always_inline’
|
||
static __always_inline __u16 __swab16p(const __u16 *p)
|
||
|
||
Fix this by replacing the inclusion of linux/compiler.h with
|
||
linux/stddef.h to ensure that we pick up that definition if required,
|
||
without relying on it's indirect inclusion. compiler.h is then included
|
||
indirectly, via stddef.h.
