Name:print a full list of all partitions - intended for places where the root* filesystem can't be mounted and thus to give the victim some idea of what* went wrong

Proto:void __init printk_all_partitions(void)

Type:void

Parameter:Nothing

951  When dev = class_dev_iter_next( & iter) cycle

962  If get_capacity(disk) == 0 || flags & GENHD_FL_SUPPRESS_PARTITION_INFO Then Continue
971  disk_part_iter_init - initialize partition iterator*@piter: iterator to initialize*@disk: disk to iterate over*@flags: DISK_PITER_* flags* Initialize @piter so that it iterates over partitions of @disk.* CONTEXT:* Don't care.
972  When part = disk_part_iter_next - proceed iterator to the next partition and return it*@piter: iterator of interest* Proceed @piter to the next partition and return it.* CONTEXT:* Don't care. cycle
973  is_part0 = part == part0
975  printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
980  If is_part0 Then
986  Else printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
989  disk_part_iter_exit - finish up partition iteration*@piter: iter of interest* Called when iteration is over. Cleans up @piter.* CONTEXT:* Don't care.
