I audited LTS kernels against bees's shiny new kernel bug tracking
table[1], and found some fixes are missing in LTS kernels:
39dba8739c4e btrfs: do not resolve backrefs for roots that are
being deleted (missing in 4.19 and 5.4, maybe not relevant for
4.14 and earlier, patch confirmed to fix a deadlock in 5.4)
4ea748e1d2c9 Btrfs: fix deadlock between clone/dedupe and rename
(merge conflict with kernels before 5.0, bug goes back to 4.4)
62d54f3a7fa2 Btrfs: fix race between send and deduplication that
lead to failures and crashes (merge conflict with kernels before
5.0, relevant on 4.4 and later)
I didn't look at patches that were missing on LTS further back than 4.14.
One didn't get flagged for -stable. The other two will not cherry-pick
cleanly and need a backport.
