Hi, I have an older qemu VM image that i sometimes use for testing. It stopped booting with 4.13-4.14 because it couldn't run init. It uses ext3 for the root file system.
I instrumented the code and found that it failed to follow the /lib/ld-linux.so.2 -> ld-2.3.6.so symlink for init's ELF interpreter. I bisected it to down to commit 407cd7fb83c0ebabb490190e673d8c71ee7df97e (refs/bisect/bad) Author: Tahsin Erdogan <[email protected]> Date: Tue Jul 4 00:11:21 2017 -0400 ext4: change fast symlink test to not rely on i_blocks when I revert this commit 4.14 my VM runs fine again.
