Subject: Re: [GIT, RFC] Killing the Big Kernel Lock
Date: Wed, 24 Mar 2010 14:53:07 -0700	[thread overview]
Message-ID: <adavdclz8sc.fsf@roland-alpha.cisco.com> (raw)
In-Reply-To: <201003242240.54907.arnd@arndb.de> (Arnd Bergmann's message of "Wed, 24 Mar 2010 22:40:54 +0100")

Hi Arnd,

Interesting work.  For the drivers/infiniband part, it seems maybe all
these drivers should be using no_llseek instead of default_llseek?  (or
is it better style to use nonseekable_open()?)  Certainly as far as I
can tell, nothing in drivers/infiniband pays any attention to f_pos.

Also, is there a reason why you add "#include <linux/smp_lock.h>" to all
the files where you also do ".llseek  = default_llseek"?

In any case I can at least take care of the llseek stuff for 2.6.35.

 - R.
