Btrfs send/scrub/defrag/qgroup need to walk backrefs,this test
is to make sure iterating backrefs with ulist is working and don't
cause a kernel panic here.

The backref walking code will search down to the key it is looking for and then
proceed to walk _all_ of the extents on the file until it hits the end. This is
suboptimal with large files, we only need to look for as many extents as we have
references for that inode. I have a testcase that

On one hand, one always hears that defragmentation of SSD is a no-no,

I would like to clarify a bit on how the fsync works in btrfs. The log

prior to the fsync, correct? It does not log the data extents of
