Subject: fault-inject: improve build for CONFIG_FAULT_INJECTION=n
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fault-inject.h users across the kernel need to add a lot of #ifdef
CONFIG_FAULT_INJECTION to cater for shortcomings in the header.  Make
fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs
for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and
should_fail() to allow removal of conditional compilation.

[akpm@linux-foundation.org: repair fallout from no longer including debugfs.h into fault-inject.h]
[akpm@linux-foundation.org: fix drivers/misc/xilinx_tmr_inject.c]
[akpm@linux-foundation.org: Add debugfs.h inclusion to more files, per Stephen]
