The current version of the header file include/linux/ratelimit.h
triggers false positives when the compiler flag
-Wmissing-field-initializers is specified. The header file
include/linux/ratelimit.h is included directly or indirectly by many
other header files -- inclusion of this file can't be avoided. The
above patch suppresses these false positives by converting the
initializers to C99 style, such that kernel developers who want to
check their code through -Wmissing-field-initializers can use this
compiler flag.  And I do not have plans to send patches for converting
initializers to C99-style for any .c file.
