Both patches are based on the 3.12-rc3 tag. This was tested on a Pandaboard with partial hibernation support, and compiled for x86. [PATCH 1/2] init/do_mounts.c: ignore final \n in name_to_dev_t init/do_mounts.c | 23 ++++++++++++++++++----- 1 file changed, 18 insertions(+), 5 deletions(-) Changes name_to_dev_t to handle a trailing newline in the input buffer, which will allow name_to_dev_t to be used directly with user buffers without requiring a copy. Also adds a const to the name parameter which reflects how name_to_dev_t is treating the input buffer currently. This also allows direct use of user buffers (from resume_store for example). [PATCH 2/2] PM / Hibernate: use name_to_dev_t to parse resume kernel/power/hibernate.c | 15 ++++----------- 1 file changed, 4 insertions(+), 11 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 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
