Sounds pretty XY to me. What are you actually trying to achieve?– Daniel BCommented Jul 18, 2014 at 8:18

7It took my Raspberry Pi multiple hours to finish ext4lazyinit on an external hard drive. I wanted to test if the hd spins down correctly after some time of inactivity however that wasn't possible due to ext4lazyinit. After looking at some kernel code (github.com/torvalds/linux/blob/master/fs/ext4/super.c#L2931) it seems not possible to force the thread to finish since the delays are somewhat hardcoded. That is however no definitive answer, I am no kernel nor ext4 expert and I just took a glimpse at that function.– MariusCommented Jul 18, 2014 at 9:29

@Marius You are correct that the delay is hard-coded.– Moshe KatzCommented Sep 14, 2016 at 18:49

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
