 741  * seems to want to inline this function into ieee80211_ioctl()
 742  * (which is the only routine that calls it). When this happens,
 743  * ieee80211_ioctl() ends up consuming an additional 2K of stack
 744  * space. (Exactly why it needs so much is unclear.) The problem
 745  * is that it's possible for ieee80211_ioctl() to invoke other
 746  * routines (including driver init functions) which could then find
 747  * themselves perilously close to exhausting the stack.
 748  *
 749  * To avoid this, we deliberately prevent gcc from inlining this
 750  * routine. Another way to avoid this is to use less agressive
 751  * optimization when compiling this file (i.e. -O instead of -O2)
 752  * but special-casing the compilation of this one module in the
 753  * build system would be awkward.
