Help text

Which block device should be used for pstore/blk.

It accepts the following variants: 1) <hex_major><hex_minor> device number in hexadecimal representation, with no leading 0x, for example b302. 2) /dev/<disk_name> represents the device name of disk 3) /dev/<disk_name><decimal> represents the device name and number of partition - device number of disk plus the partition number 4) /dev/<disk_name>p<decimal> - same as the above, this form is used when disk name of partitioned disk ends with a digit. 5) PARTUUID=00112233-4455-6677-8899-AABBCCDDEEFF representing the unique id of a partition if the partition table provides it. The UUID may be either an EFI/GPT UUID, or refer to an MSDOS partition using the format SSSSSSSS-PP, where SSSSSSSS is a zero- filled hex representation of the 32-bit "NT disk signature", and PP is a zero-filled hex representation of the 1-based partition number. 6) PARTUUID=<UUID>/PARTNROFF=<int> to select a partition in relation to a partition with a known unique id. 7) <major>:<minor> major and minor number of the device separated by a colon.

NOTE that, both Kconfig and module parameters can configure pstore/blk, but module parameters have priority over Kconfig.
