From 1cf96da241f489fd29fe564c8fc045e51b5269b8 Mon Sep 17 00:00:00 2001 From: wang di Date: Sat, 28 Jan 2017 19:05:25 -0500 Subject: [PATCH] staging: lustre: lmv: remove nlink check in lmv_revalidate_slaves If an application attempts to remove millions of files in a single directory it will fail. This failure was tracked down to the nlink < 2 check in lmv_revalidate_slaves, because after nlink reaches to maximum value of LDISKFS_LINK_MAX (65000), the nlink broadcast back from the server will be reported as one. The return value of 1 is not invalid so lets remove the check.
