Subject: [Bug 217965] ext4(?) regression since 6.5.0 on sata hdd

https://bugzilla.kernel.org/show_bug.cgi?id=217965

--- Comment #8 from Ojaswin Mujoo (ojaswin.mujoo@....com) ---
Hey Ivan, thanks! 

Seems like stripe mount option is automatically added if the filesystem is made
using stride or stripe-width options during mkfs time. 

Can you kindly perform the below steps as well to further help narrow this
issue down:

1. Mount FS with the usual options (including using stripe=32752). 
2. Once mounted, run:

$ echo "0" > /sys/fs/ext4/sdb2/mb_best_avail_max_trim_order

This might need sudo. Basically this disables one of the allocator feature that
was added in 6.5.

3. Run the workload again and see if the issue is still visible.

Regards,
ojaswin
