[PATCH 0/2 -mm] kexec based hibernation -v5

2007-10-10 Thread Huang, Ying
Kexec base hibernation has some potential advantages over uswsusp and TuxOnIce (suspend2). Some most obvious advantages are: 1. The hibernation image size can exceed half of memory size easily. 2. The hibernation image can be written to and read from almost anywhere, such as USB disk, NFS. 3.
