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 fs/btrfs/disk-io.c | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) -- 2.17.1
