Re: rt patch

Using a more recent system, I have following mistakes:
trying to patch a file not present in the kernel.
Sincerely, I do not understand what is the problem !

Perhaps you used the wrong -p or --strip option?

|Subject: [PATCH] Revert "rwsem-rt: Do not allow readers to nest"
|
|This behaviour is required by cpufreq and its logic is "okay": It does a
|read_lock followed by a try_read_lock.
|Lockdep warns if one try a read_lock twice in -RT and vanilla so it
|should be good. We still only allow multiple readers as long as it is in
|the same process.
