Subject: [PATCH 4/5] partitions: Add conditionals and static inline stubs to
helpers in headers
From: John Anthony Kazos Jr. <jakj@...-k-j.com>
Functions of the form adfspart_check_FOO and foo_partition defined in
fs/partitions/*.h are helper functions called in a deliberate order by
check_partition in check.c. Add conditional-compilation directives and
static inline no-op functions to allow code to indiscriminately call these
functions irrespective of whether they do anything, removing the necessity
of oodles of #ifdef/#endif in function bodies.
Signed-off-by: John Anthony Kazos Jr. <jakj@...-k-j.com>
---
The next patch changes the check.c code to use these function definitions
in a nicer way.
