      [PATCH] swsusp: userland interface · 6e1819d6
      Rafael J. Wysocki 提交于
      This patch introduces a user space interface for swsusp.
      
      The interface is based on a special character device, called the snapshot
      device, that allows user space processes to perform suspend and resume-related
      operations with the help of some ioctls and the read()/write() functions.
       Additionally it allows these processes to allocate free swap pages from a
      selected swap partition, called the resume partition, so that they know which
      sectors of the resume partition are available to them.
      
      The interface uses the same low-level system memory snapshot-handling
      functions that are used by the built-it swap-writing/reading code of swsusp.
      
      The interface documentation is included in the patch.
      
      The patch assumes that the major and minor numbers of the snapshot device will
      be 10 (ie.  misc device) and 231, the registration of which has already been
      requested.
