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
iget_locked uses ifind_fast to search for the inode specified by ino in
the inode cache and if present it is returned 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, get_new_inode_fast is called to allocate
a new inode and this is returned locked, hashed, and with the I_NEW
flag set. The file system gets to fill it in before unlocking it via
unlock_new_inode.
