From: Roland Dreier Date: Sat, 10 Jan 2009 06:27:42 +0000 (-0800) Subject: driver core: Convert '/' to '!' in dev_set_name() X-Git-Tag: v2.6.29-rc3~28^2~4 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7143f7a1a3603002e4ef3719fa92e8dd6e607099;p=pandora-kernel.git driver core: Convert '/' to '!' in dev_set_name() Commit 3ada8b7e ("block: struct device - replace bus_id with dev_name(), dev_set_name()") deleted the code in register_disk() that changed a '/' to a '!' in the device name when registering a disk, but dev_set_name() does not perform this conversion. This leads to amusing problems with disks that have '/' in their names: for example a failure to boot with the root partition on a cciss device, even though the kernel says it knows about the root device: VFS: Cannot open root device "cciss/c0d0p6" or unknown-block(0,0) Please append a correct "root=" boot option; here are the available partitions: 6800 71652960 cciss/c0d0 driver: cciss 6802 1 cciss/c0d0p2 6805 2931831 cciss/c0d0p5 6806 34354908 cciss/c0d0p6 6810 71652960 cciss/c0d1 driver: cciss Fix this by adding code to change '/' to '!' in dev_set_name() to handle this until dev_set_name() is converted to use kobject_set_name().
