5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josef Bacik <josef@xxxxxxxxxxxxxx>
commit 11aeb97b45ad2e0040cbb2a589bc403152526345 upstream.
We have a random schedule_timeout() if the current transaction is
committing, which seems to be a holdover from the original delalloc
reservation code.
Remove this, we have the proper flushing stuff, we shouldn't be hoping
for random timing things to make everything work. This just induces
latency for no reason.
