/* the ref bit is tricky. We have to make sure it is set

/*
* The TREE_REF bit is first set when the extent_buffer is added
* to the radix tree. It is also reset, if unset, when a new reference
* is created by find_extent_buffer.
*
* Once the ref bit is set, it won't go away while the
* buffer is dirty or in writeback, and it also won't
* go away while we have the reference count on the
* eb bumped.
* It is only cleared in two cases: freeing the last non-tree
* reference to the extent_buffer when its STALE bit is set or
* calling releasepage when the tree reference is the only reference.
*
* We can't just set the ref bit without bumping the
* ref on the eb because free_extent_buffer might
* see the ref bit and try to clear it. If this happens
* free_extent_buffer might end up dropping our original
* ref by mistake and freeing the page before we are able
* to add one more ref.
* In both cases, care is taken to ensure that the extent_buffer's
* pages are not under io. However, releasepage can be concurrently
* called with creating new references, which is prone to race
* conditions between the calls to check_buffer_tree_ref in those
* codepaths and clearing TREE_REF in try_release_extent_buffer.
*
* So bump the ref count first, then set the bit. If someone
* beat us to it, drop the ref we added.
* The actual lifetime of the extent_buffer in the radix tree is
* adequately protected by the refcount, but the TREE_REF bit and
* its corresponding reference are not. To protect against this
* class of races, we call check_buffer_tree_ref from the codepaths
* which trigger io after they set eb->io_pages. Note that once io is
* initiated, TREE_REF can no longer be cleared, so that is the
* moment at which any such race is best fixed.
