Subject: ftrace: make the task state char-string visible to all
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7c731e0a495e25e79dc1e9e68772a67a55721a65;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ftrace: make the task state char-string visible to all

The tracer wants to be able to convert the state number
into a user visible character. This patch pulls that conversion
string out the scheduler into the header. This way if it were to
ever change, other parts of the kernel will know.
