Btrfs: Fix a number of inline extent problems that Yan Zheng reported.
The fixes do a number of things: 1) Most btrfs_drop_extent callers will try to leave the inline extents in place. It can truncate bytes off the beginning of the inline extent if required. 2) writepage can now update the inline extent, allowing mmap writes to go directly into the inline extent. 3) btrfs_truncate_in_transaction truncates inline extents 4) extent_map.c fixed to not merge inline extent mappings and hole mappings together Signed-off-by: Chris Mason <chris.mason@oracle.com>
