Merge tag 'for-6.3-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"Two patches fixing the problem with aync discard.
The default settings had a low IOPS limit and processing a large batch
to discard would take a long time. On laptops this can cause increased
power consumption due to disk activity.
As async discard has been on by default since 6.2 this likely affects
a lot of users.
Summary:
- increase the default IOPS limit 10x which reportedly helped
- setting the sysfs IOPS value to 0 now does not throttle anymore
allowing the discards to be processed at full speed. Previously
there was an arbitrary 6 hour target for processing the pending
batch"
