 /*
  * blkdev - the block device to use for pstore storage
- *
- * Usually, this will be a partition of a block device.
- *
- * blkdev accepts the following variants, when built as a module:
- * 1) /dev/<disk_name> represents the device number of disk
- * 2) /dev/<disk_name><decimal> represents the device number
- *    of partition - device number of disk plus the partition number
- * 3) /dev/<disk_name>p<decimal> - same as the above, that form is
- *    used when disk name of partitioned disk ends on a digit.
- *
- * blkdev accepts the following variants when built into the kernel:
- * 1) <hex_major><hex_minor> device number in hexadecimal representation,
- *    with no leading 0x, for example b302.
- * 2) 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.
- * 3) PARTUUID=<UUID>/PARTNROFF=<int> to select a partition in relation to
- *    a partition with a known unique id.
- * 4) <major>:<minor> major and minor number of the device separated by
- *    a colon.
+ * See Documentation/admin-guide/pstore-blk.rst for details.
