-SNAPSHOT_SET_SWAP_FILE - set the resume partition (the last ioctl() argument
-       should specify the device's major and minor numbers in the old
-       two-byte format, as returned by the stat() function in the .st_rdev
-       member of the stat structure)
 SNAPSHOT_SET_SWAP_AREA - set the resume partition and the offset (in 
        units) from the beginning of the partition at which the swap header is
        located (the last ioctl() argument should point to a struct
        resume_swap_area, as defined in kernel/power/power.h, containing the
-       resume device specification, as for the SNAPSHOT_SET_SWAP_FILE ioctl(),
-       and the offset); for swap partitions the offset is always 0, but it is
-       different to zero for swap files (please see
+       resume device specification and the offset); for swap partitions the
+       offset is always 0, but it is different from zero for swap files (see
        Documentation/swsusp-and-swap-files.txt for details).
-       The SNAPSHOT_SET_SWAP_AREA ioctl() is considered as a replacement for
-       SNAPSHOT_SET_SWAP_FILE which is regarded as obsolete.   It is
-       recommended to always use this call, because the code to set the resume
-       partition may be removed from future kernels
 SNAPSHOT_PLATFORM_SUPPORT - enable/disable the hibernation platform support,
        depending on the argument value (enable, if the argument is nonzero)
