By scanning inode items,\nwe know which chunks of inode numbers are free, and we cache them in\nan rb-tree.\n\nBecause we are searching the commit root, we have to carefully handle the\ncross-transaction case.\n\nThe rb-tree is a hybrid extent+bitmap tree, so if we have too many small\nchunks of inode numbers, we\u0027ll use bitmaps. Initially we allow 16K ram\nof extents, and a bitmap will be used if we exceed this threshold. The\nextents threshold is adjusted in runtime.\n\nSigned-off-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\n"
