Subject: [RFC PATCH v3 30/61] e2fsck: move some fixes out of parallel pthreads
From: Wang Shilong <wshilong@....com>
We could only use @found_map_block to find free blocks
after we have collectd all used blocks, so something like
handle_fs_bad_blocks(), ext2fs_create_resize_inode(),
e2fsck_pass1_dupblocks() really should be handled after
all threads has been finished.
