X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dd9963f9dd0985e16e878fd3632ecadfc54d3fbb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [S390] cio: subchannels in no-path state. Subchannel may incorrectly remain in state no-path after channel paths have reappeared. Currently the scan for subchannels which are using a channel path ends at the first occurrence if a full link address was provided by the channel subsystem. The scan needs to continue over all subchannels.
