-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 <PAGE_SIZE>
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)
