Don't print out an error with the driver sees EPROBE_DEFER when
attempting to get the gpio. These errors are usually transient; the

Even if --symfs is used to point to the debug binaries, we send in the
non-debug filenames to libunwind, which leads to libunwind not finding
the debug frame. Fix this.

Hi,
I received some reports of mkfs.ext4 on an SD card triggering the OOM

made a reproducible setup of this by using null_blk with a large
