Hi Gang, GLOBAL_INODE_ALLOC_SYSTEM_INODE is used for system file inodes allocation, you can refer mkfs.c for details.

These two are not used. Maybe left for future extend.

[Ocfs2-devel] What are the purposes of GLOBAL_INODE_ALLOC_SYSTEM_INODE and BAD_BLOCK_SYSTEM_INODE system file
Hello Guys, If you use debugfs.ocfs2 to list system files for a ocfs2 file system, you can find these two system files. sles12sp1-node1:/ # debugfs.ocfs2 /dev/sdb1 debugfs.ocfs2 1.8.2 debugfs: ls // 6 16 12 . 6 16 22 .. 7 24 10 1 bad_blocks << == BAD_BLOCK_SYSTEM_INODE 8 32 18 1 global_inode_alloc << == GLOBAL_INODE_ALLOC_SYSTEM_INODE But, What are the purposes of GLOBAL_INODE_ALLOC_SYSTEM_INODE and BAD_BLOCK_SYSTEM_INODE system file? For BAD_BLOCK_SYSTEM_INODE system file, it looks to be used to store bad blocks for a file system partition, but from the code, there is not any code for this system file. For GLOBAL_INODE_ALLOC_SYSTEM_INODE system file, there is also not any code for it, what is the purpose of this file ?
