[XFS] fix ASSERT and ASSERT_ALWAYS

2007-09-05T04:49:30Z

- remove the != 0 inside the unlikely in ASSERT_ALWAYS because sparse now complains about comparisons between pointers and 0 - add a standalone ASSERT implementation because defining it to ASSERT_ALWAYS means the string is expanded before the token passing stringification. This way we get the actual content of the assertion in the assfail message and don't overflow sparse's stringification buffer leading to sparse error messages.

[XFS] Keep stack usage down for 4k stacks by using noinline.

2007-02-10T07:34:56Z

gcc-4.1 and more recent aggressively inline static functions which increases XFS stack usage by ~15% in critical paths. Prevent this from occurring by adding noinline to the STATIC definition. Also uninline some functions that are too large to be inlined and were causing problems with CONFIG_FORCED_INLINING=y. Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.

[XFS] Prevent buffer overrun in cmn_err().

2007-02-10T07:34:38Z

The message buffer used by cmn_err() is only 256 bytes and some CXFS messages were exceeding this length. Since we were using vsprintf() and not checking for buffer overruns we were clobbering memory beyond the buffer. The size of the buffer has been increased to 1024 bytes so we can capture these larger messages and we are now using vsnprintf() to prevent overrunning the buffer size.
