D_INVALIDATE(9)                           The Linux VFS                           D_INVALIDATE(9)



NAME
       d_invalidate - detach submounts, prune dcache, and drop

SYNOPSIS
       void d_invalidate(struct dentry * dentry);

ARGUMENTS
       dentry
           dentry to invalidate (aka detach, prune and drop)

DESCRIPTION
       no dcache lock.

       The final d_drop is done as an atomic operation relative to rename_lock ensuring there are
       no races with d_set_mounted. This ensures there are no unhashed dentries on the path to a
       mountpoint.
