Description
In the Linux kernel, the following vulnerability has been resolved:
btrfs: add missing RCU unlock in error path in try_release_subpage_extent_buffer()
Call rcu_read_lock() before exiting the loop in
try_release_subpage_extent_buffer() because there is a rcu_read_unlock()
call past the loop.
This has been detected by the Clang thread-safety analyzer.
