IGET_LOCKED(9) The Linux VFS IGET_LOCKED(9)NAME
iget_locked - obtain an inode from a mounted file system
struct inode * iget_locked(struct super_block * sb, unsigned long ino);
super block of file system
inode number to get
Search for the inode specified by ino in the inode cache and if present return it with an increased reference count. This is for file
systems where the inode number is sufficient for unique identification of an inode.
If the inode is not in cache, allocate a new inode and return it locked, hashed, and with the I_NEW flag set. The file system gets to fill
it in before unlocking it via unlock_new_inode.

matchpathcon_checkmatches, matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether
any specification index has no matches with any inode. Maintenance and statistics on inode associations.
void matchpathcon_checkmatches(char *str);
int matchpathcon_filespec_add(ino_t ino, int specind, const char *file);
matchpathcon_checkmatches checks whether any specification has no matches and reports them. The str argument is used as a prefix for any
matchpathcon_filespec_add maintains an association between an inode ino and a specification index specind, and checks whether a conflicting
specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two speci-
fications based on their order in the file context configuration. Returns the specification index used or -1 on error.
matchpathcon_filespec_destroy destroys any inode associations that have been added, e.g. to restart for a new filesystem.
matchpathcon_filespec_eval displays statistics on the hash table usage for the inode associations.
Returns zero on success or -1 otherwise.
