Sure Wendy. Here it is,
"fs/gfs2/inode.c" 1256
struct inode *gfs2_ilookup(struct super_block *sb, struct gfs2_inum_host
*inum)
{
return ilookup5(sb, (unsigned long)inum->no_formal_ino,
iget_test, inum);
}
static struct inode *gfs2_iget(struct super_block *sb, struct
gfs2_inum_host *inum)
{
return iget5_locked(sb, (unsigned long)inum->no_formal_ino,
iget_test, iget_set, inum);
}
BTW - this code is from kernel version 2.6.20.1.
Thanks,
Sridhar
