IUNIQUE(9) The Linux VFS IUNIQUE(9)NAME
iunique - get a unique inode number
ino_t iunique(struct super_block * sb, ino_t max_reserved);
highest reserved inode number
Obtain an inode number that is unique on the system for a given superblock. This is used by file systems that have no natural permanent
inode numbering system. An inode number is returned that is higher than the reserved limit but unique.
With a large number of inodes live on the file system this function currently becomes quite slow.

CLRI(8) BSD System Manager's Manual CLRI(8)NAME
clri -- clear an inode
clri special_device inode_number ...
Clri is obsoleted for normal file system repair work by fsck(8).
Clri zeros out the inodes with the specified inode number(s) on the filesystem residing on the given special_device. The fsck(8) utility is
usually run after clri to reclaim the zero'ed inode(s) and the blocks previously claimed by those inode(s). Both read and write permission
are required on the specified special_device.
The primary purpose of this routine is to remove a file which for some reason is not being properly handled by fsck(8). Once removed, it is
anticipated that fsck(8) will be able to clean up the resulting mess.
SEE ALSO fsck(8), fsdb(8), icheck(8), ncheck(8)BUGS
If the file is open, the work of clri will be lost when the inode is written back to disk from the inode cache.
