| H A D | discard.h | dfb79ddb Fri Dec 13 18:22:20 CST 2019 Dennis Zhou <dennis@kernel.org> btrfs: track discardable extents for async discard
The number of discardable extents will serve as the rate limiting metric
for how often we should discard. This keeps track of discardable extents
in the free space caches by maintaining deltas and propagating them to
the global count.
The deltas are calculated from 2 values stored in PREV and CURR entries,
then propagated up to the global discard ctl. The current counter value
becomes the previous counter value after update.
