NAME

iunique - get a unique inode number

SYNOPSIS

ino_t iunique(struct super_block * sb, ino_t max_reserved);

DESCRIPTION

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.
