Subject: kmemtrace, fs: fix linux/fdtable.h header file dependencies
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=21e5445928af0d80f7cf803a77f2b65e9e147890;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

kmemtrace, fs: fix linux/fdtable.h header file dependencies

Impact: cleanup

We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
changes), but this is not possible currently without breaking the
build because fdtable.h has an implicit include file dependency: it
uses __init does not include init.h.

This can cause build failures on non-x86 architectures:

 /home/mingo/tip/include/linux/fdtable.h:66: error: expected '=', ',',
 ';', 'asm' or '__attribute__' before 'files_defer_init'
 make[2]: *** [fs/locks.o] Error 1

We got this header included indirectly via rcupdate.h's percpu.h
inclusion - but if that is not there the build will break.

Fix it.
