[PATCH 0/4] Small QOI fixes for transaction_kthread

[Nikolay Borisov <nborisov@suse.com>]

Following 4 patches make transaction_kthread code slitghly more user friendly.
Namely, patch 1 convert from open-coded multiplicaiton by HZ to using
msecs_to_jiffies helper. Patch 2 relies on the observation that the running
transaction is obtained under trans_lock so an extra check can be removed.
Patch 3/4 could possibly be squashed into 1 but the net effect is that the code
is more intuitive when sleeping in case a lower interval than commit_trans has
elapsed.


This has survived full xfstest run.

Nikolay Borisov (4):
  btrfs: Use helpers to convert from seconds to jiffies in
    transaction_kthread
  btrfs: Remove redundant check
  btrfs: Record delta directly in transaction_kthread
  btrfs: Be smarter when sleeping in transaction_kthread
