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.
