| |
Using the "resume" kernel parameter together with an initramfs revealed a bug that causes removal of the /sys directory in the initramfs' tmpfs, making the system unbootable.
The source of the problem is that the try_name() function removes the /sys directory unconditionally, instead of removing it only when it has been created by try_name().
The attached patch only removes /sys if it has been created before.
Please CC me, I'm not on lkml.
