I read topic "Bug 203973 - VFAT filesystem causes errors when opened through Calibre and disconnects device" (CLOSED WILL_NOT_FIX)

In real life seems this issue is affecting Kindle only when it is used with Calibre software.

As you see in my research, problem is still active for today. Even on latest Calibre, Linux Kernel and Kindle firmware.

As I read in that topic, problem comes with 4.19.50+ kernel.

Maybe you can detect if (Kernel version >4.19.50 and device is Kindle) => do not use any sync/flush calls ?

Or just disable all fsync() for Kindle under any Linux (because 4.19.50 is old kernel for today) ?
