IGET_LOCKED(9)							   The Linux VFS						    IGET_LOCKED(9)

NAME
       iget_locked - obtain an inode from a mounted file system

SYNOPSIS
       struct inode * iget_locked(struct super_block * sb, unsigned long ino);

ARGUMENTS
       sb
	   super block of file system

       ino
	   inode number to get

DESCRIPTION
       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.
