4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tobias Klauser <tklauser@xxxxxxxxxx>
commit 9a05e7541c39680d28ecf91892338e074738d5fd upstream.
With compilers which follow the C99 standard (like modern versions of
gcc and clang), "extern inline" does the opposite thing from older
versions of gcc (emits code for an externally linkable version of the
inline function).
"static inline" does the intended behavior in all cases instead.
Description taken from commit 6d91857d4826 ("staging, rtl8192e,
LLVMLinux: Change extern inline to static inline").
This also fixes the following GCC warning when building with CONFIG_PM
disabled:
./include/linux/blkdev.h:1143:20: warning: no previous prototype for 'blk_set_runtime_active' [-Wmissing-prototypes]
Fixes: d07ab6d11477 ("block: Add blk_set_runtime_active()")
