The pernicious USB-stick stall problem

10 years later, this is still causing headaches for many users
I keep imagining a new user going to linux and facing this problem, having to wait 2 hours to unmount his usb stick 2.0 and having to go out looking for a manual solution on google
In my case i am not a new user but i had this problem and i ended up finding a solution and now i can unmount the pendrive as soon as the copy progress bar ends (just like it is in windows)
correction:
create the file:
/etc/udev/rules.d/60-usb-dirty-pages-udev.rules

with the following content:
ACTION=="add", KERNEL=="sd[a-z]", SUBSYSTEM=="block", ENV{ID_USB_TYPE}=="disk", RUN+="/usr/bin/bash -c 'echo 1 > /sys/block/%k/bdi/strict_limit; echo 16777216 > /sys/block/%k/bdi/max_bytes'"

then restart your machine !

After so many years this should already have a definitive solution in the kernel and not need manual intervention by the user.
It's this kind of thing that keeps new users away from the system
