Subject: nfs: idr_destroy() no longer needs idr_remove_all()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d97bec801d726abb14ab0e18d6aef5293580a467;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

nfs: idr_destroy() no longer needs idr_remove_all()

idr_destroy() can destroy idr by itself and idr_remove_all() is being
deprecated.  Drop reference to idr_remove_all().  Note that the code
wasn't completely correct before because idr_remove() on all entries
doesn't necessarily release all idr_layers which could lead to memory
leak.
