Subject[PATCH v2 RFT 0/2] PM / Hibernate: sysfs resume
Date
Patchset related to hibernation resume: one enhancement to make the use
of an existing file more general and one documentation update.

Both patches are based on the 3.11-rc6 tag. This was tested on a
Pandaboard with partial hibernation support, and compiled on x86.

Further testing is needed on other platforms. Please let me know if
you're able to verify this on any other systems.

[PATCH 1/2] PM / Hibernate: use name_to_dev_t to parse resume
Use name_to_dev_t to parse the /sys/power/resume file making the
syntax more flexible. It supports the previous use syntax
and additionally can support other formats such as
/dev/devicenode and UUID= formats.

By changing /sys/debug/resume to accept the same syntax as
the resume=device parameter, we can parse the resume=device
in the initrd init script and use the resume device directly
from the kernel command line.

[PATCH 2/2] PM / Hibernate: add section for resume options
This adds a small section to the swsusp.txt file to address the
options for resuming. This comments on the manual resume
option which is used when resorting to an initrd or initramfs
for resuming. Resuming from late init is discussed later in
the document, but it seemed appropriate to list them together.

Sebastian
