Subject: perf: Fix callchain hit bad cast on ascii display
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d425de5436a620de506f9e4119bf8daa1cb93718;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

perf: Fix callchain hit bad cast on ascii display

ipchain__fprintf_graph() casts the number of hits in a branch as an
int, which means we lose its highests bits.

This results in meaningless number of callchain hits in perf.data
that have a high number of hits recorded, typically those that have
callchain branches hits appearing more than INT_MAX. This happens
easily as those are pondered by the event period.
