Description

Is your feature request related to a problem? Please describe.
I need to mount to get the files in the EROFS filesystem image.
This requires the support of the Linux kernel.
EROFS has entered the mainline in kernel version 5.4.
Unfortunately, WSL does not have this support when compiling the kernel.

Release information: Ubuntu 21.04 5.10.16.3-microsoft-standard-WSL2

Describe the solution you'd like
Add EROFS filesystem support to WSL.

Describe alternatives you've considered
No alternative available. No tool can unpack the image of the EROFS filesystem.

Additional context

$ zcat /proc/config.gz | grep EROFS
# CONFIG_EROFS_FS is not set

Research direction

No source file or test is named. Start by inspecting the WSL kernel build configuration for CONFIG_EROFS_FS and compare it with the reported WSL2 kernel; done means an EROFS image can be mounted and /proc/config.gz reports filesystem support.
