Subject: [PATCH] sparse: avoid clash with __bitwise and __force from 4.10
|
|
|
ecbff1 |
linux/types.h (#5061)
|
|
|
ecbff1 |
|
|
|
ecbff1 |
It also used __bitwise and __force. It seems easier to rename
|
|
|
ecbff1 |
our versions since they are local to this one single header.
|
|
|
ecbff1 |
|
|
|
ecbff1 |
Also, undefine them afteerwards, so that we don't pollute the
|
|
|
ecbff1 |
preprocessor macro namespace.
|
|
|

|
|

(cherry picked from commit dc66f33a16596c2886a24da12e56ec096214e124)
