does this actually work with mainline kernel sources?
Sean Paul did look at making the edp work on Chromebooks recently,
but it seemed ther
Without this patch, it will cause all the free segments using up in some
corner case. For example, there are 100 segments, and 20 of them are
reserved for ovp. If 79 segments are full of data, segment 80 becomes
CURSEG segment, write 512 blocks and then delete 511 blocks. Since it is

Fix the kerneldoc comments of __device_suspend_noirq(),
__device_suspend_late() and __device_suspend() where the function
names in kerneldoc don't match the actual names of the functions.
Also fix the device_resume_noirq() kerneldoc comment which mentions

The PM QoS flag PM_QOS_FLAG_REMOTE_WAKEUP is not used consistently
and the vast majority of code simply assumes that remote wakeup
should be enabled for devices in runtime suspend if they can
generate wakeup signals, so drop it.

When poweroff L1 Guest with L2 guset on L1, it exists a path to
trigger a bad_page bug_on.
!page_count(pfn_to_page(pfn)) Warning in mmu_spte_clear_track_bits will
appear before,then it may set A/D bit for the freed page and trigger a
bad_page bug_on.
