Subject: rcu: Make rcu node arrays static const char * const
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b99d3975245fc4814df6af2e7107d8f5e5dbe78;p=karo-tx-linux.git

rcu: Make rcu node arrays static const char * const

Those two arrays are being passed to lockdep_init_map(), which expects
const char *, and are stored in lockdep_map the same way.
