In insert_inline_extent(), there is an if statement on line 181 to check
whether compressed_pages is NULL:
if (compressed_size && compressed_pages)
When compressed_pages is NULL, compressed_pages is used on line 215:
cpage = compressed_pages[i];
Thus, a possible null-pointer dereference m

Btrfs uses several different ways to drop a subvolume. Some methods are
designed to reduce the modification to extent tree.
This design can be very confusing if not familiar with
btrfs_drop_snapshot().
Before wasting time of newcomers, just add some explanation.
Also add some basic comment for me
