From 7989cb8ef5dbc1411d3be48218c7b25ef6e71699 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Sat, 10 Feb 2007 18:34:56 +1100 Subject: [XFS] Keep stack usage down for 4k stacks by using noinline. 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.
