VFS_UNLINK(9)                             The Linux VFS                             VFS_UNLINK(9)



NAME
       vfs_unlink - unlink a filesystem object

SYNOPSIS
       int vfs_unlink(struct inode * dir, struct dentry * dentry,
                      struct inode ** delegated_inode);

ARGUMENTS
       dir
           parent directory

       dentry
           victim

       delegated_inode
           returns victim inode, if the inode is delegated.

DESCRIPTION
       The caller must hold dir->i_mutex.

       If vfs_unlink discovers a delegation, it will return -EWOULDBLOCK and return a reference
       to the inode in delegated_inode. The caller should then break the delegation on that inode
       and retry. Because breaking a delegation may take a long time, the caller should drop
       dir->i_mutex before doing so.

       Alternatively, a caller may pass NULL for delegated_inode. This may be appropriate for
       callers that expect the underlying filesystem not to be NFS exported.
