ldm_debug() writes a DEBUG level message to the syslog but only if the driver was compiled with debug enabled. Otherwise, the call turns into a NOP.

Function Documentation

int ldm_partition

(

struct parsed_partitions *

state

)

ldm_partition - Find out whether a device is a dynamic disk and handle it : Partition check state including device holding the LDM Database

This determines whether the device is a dynamic disk and if so creates the partitions necessary in the gendisk structure pointed to by .

We create a dummy device 1, which contains the LDM database, and then create each partition described by the LDM database in sequence as devices 2+. For example, if the device is hda, we would have: hda1: LDM database, hda2, hda3, and so on: the actual data containing partitions.

Return: 1 Success, ->bdev is a dynamic disk and we handled it 0 Success, ->bdev is not a dynamic disk -1 An error occurred before enough information had been read Or ->bdev is a dynamic disk, but it may be corrupted
