Subject: [PATCH v4 0/2] PM / Hibernate: sysfs resume
Date: Wed, 29 Jan 2014 15:48:22 -0800 [thread overview]
Message-ID: <1391039304-3172-1-git-send-email-sebastian.capella@linaro.org> (raw)
Patchset related to hibernation resume:
- enhancement to make the use of an existing resume file more general
- add kstrimdup function which trims and duplicates a string
Both patches are based on the 3.13 tag. This was tested on a
Beaglebone black with partial hibernation support, and compiled for
x86_64.
[PATCH v4 1/2] mm: add kstrimdup function

Adds the kstrimdup function to duplicate and trim whitespace
from a string. This is useful for working with user input to
sysfs.
[PATCH v4 2/2] PM / Hibernate: use name_to_dev_t to parse resume
kernel/power/hibernate.c | 33
+++++++++++++++++----------------
1 file changed, 17 insertions(+), 16 deletions(-)
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.
Changes in v4:
--------------
* Dropped name_to_dev_t rework in favor of adding kstrimdup
* adjusted resume_store
Changes in v3:
--------------
* Dropped documentation patch as it went in through trivial
* Added patch for name_to_dev_t to support directly parsing userspace
buffer
Changes in v2:
--------------
* Added check for null return of kstrndup in hibernate.c
Thanks,
Sebastian
