fs/proc/util.c: include fs/proc/internal.h for name_to_int()

2019-01-04T21:13:45+00:00

name_to_int() is defined in fs/proc/util.c and declared in fs/proc/internal.h, but the declaration isn't included at the point of the definition. Include the header to enforce that the definition matches the declaration. This addresses a gcc warning when -Wmissing-prototypes is enabled.

proc: use do-while in name_to_int()

Gcc doesn't know that "len" is guaranteed to be >=1 by dcache and generates standard while-loop prologue duplicating loop condition. add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-27 (-27) function old new delta name_to_int 104 77 -27 Link: http://lkml.kernel.org/r/20170912195213.GB17730@avx2 Signed-off-by: Alexey Dobriyan Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
