X-Git-Tag: v2.6.18-rc2~112^2~5 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6ab4879a0d074c938fd17dba141dce042fc17bee;p=pandora-kernel.git [S390] subchannel register/unregister mutex. Add a reg_mutex to prevent unregistering a subchannel before it has been registered. Since 2.6.17, we've seen oopses in kslowcrw when a device is found to be not operational during sense id when doing initial device recognition; it is not clear yet why that particular problem was not (yet) observed with earlier kernels...
