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 include/linux/string.h | 1 + mm/util.c | 19 +++++++++++++++++++ 2 files changed, 20 insertions(+) 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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
