[btrfs-devel]two issues in btrfs-unstable

[Yan Zheng]

Hello Chris,

1.  In 'update_block_group',  when parameter 'alloc' is true,
free_space_cache isn't updated,  extent_map_radix is updated at the
same place in 0.8.  I feel it's like a typo.

2.  In btrfs_read_fs_root_no_radix,  root->root_key isn't setup. It
cause problem when drop dead root(I met a kernel Oops after mount a
unclean btrfs)

By the way,  please tell me whether you like this way to report bug
for btrfs-unstable.

Regards
YZ
