Subject: sched: Move STDL_INIT() functions out-of-line
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=91c614f09abf1d45aac6b475d82a36c704b527ee;p=users%2Fhch%2Fmisc.git

sched: Move STDL_INIT() functions out-of-line

Since all these functions are address-taken in SDTL_INIT() and called
indirectly, it doesn't really make sense for them to be inline.
