Subject: [PATCH] sb1000: reduce ioctl stack usage

From: "Randy.Dunlap" <[email-masked]>
Date: Sun, 30 Jan 2005 18:12:00 -0800

sb1000_dev_ioctl() (on i386) uses 824 bytes of stack space,
all due to overuse of inline functions.
By changing a few infrequently used functions to non-inline,
the stack usage is reduced to only 60 bytes.
Nothing in a fast path is changed.
