xfs: inactivate directory data blocks

Browse source

Teach inode inactivation to delete all the incore buffers backing a
directory.  In normal runtime this should never happen because the VFS
forbids rmdir on a non-empty directory.

In the next patch, online directory repair stands up a new directory,
exchanges it with the broken directory, and then drops the private
temporary directory.  If we cancel the repair just prior to exchanging
the directory contents, the new directory will need to be torn down.
Note: If we commit the repair, reaping will take care of all the ondisk
space allocations and incore buffers for the old corrupt directory.
