Hi all,

    Since I want to optimize the I/O performance under openwrt with USB 3.0 (mt7621 dual core),
    I had tried 3 methods to mount my vfat/exfat  format u-disk as "async" option, but failed.
   
    My OpenWRT version is 14.07, and kernel has been enable AIO support,
    method 1 :   use shell command :  mount /dev/sda1 /mnt -o rw,noatime,async
    method 2 :   use linux c function :   mount(x,x,x,"rw,async");
    method 3 :   edit /etc/config/fstab  option options 'rw,async'

    Unfortunately, none of above methods can mount the disk as "async" mode, please help me,
    Any hit will be appreciate.

Have you looked into this link

also I noticed you did something with adding squashfs and was able to do some reset, how was you able to do that? I've been using chaos calmer x86 for a year and decided to do a reset to defaults since i have a new provider and wanted to go back and start over, but if there no practical method i could just do this manually, backup and restore this manually.

The discussion might have continued from here.
