X-Git-Tag: v4.1.12-92~313^2~136
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=2d397202437f7cca38948e98183526a984aef082;p=users%2Fjedix%2Flinux-maple.git

dtrace: fix a bug in the SDT probe location generator

The generator could accidentally add the address of a non-function
identifier to the SDT list (e.g. watchdog occurs both in the
uninitialised data section (BSS) and the text section).
