Subject: perf hist: Remove the needless callchain.h include from hist.h
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=71551288d2fde0c24df3c248e3e80be92783376d;p=openwrt%2Fstaging%2Fblogic.git

perf hist: Remove the needless callchain.h include from hist.h

Nothing that is provided by callchain.h is used there, just things that
should've be directly included in hist.h, such as rbtree.h and a
map_symbol forward declaration.

Remove it so that we reduce the headers dependency tree.
