Subject: [PATCH] proc: Remove useless BKL in proc_pid_readlink
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ff9724a3f7a69f7b443c05981f84e28017c2fc5a;p=deliverable%2Flinux.git

[PATCH] proc: Remove useless BKL in proc_pid_readlink

We already call everything except do_proc_readlink outside of the BKL in
proc_pid_followlink, and there appears to be nothing in do_proc_readlink that
needs any special protection.

So remove this leftover from one of the BKL cleanup efforts.
