Subject: [PATCH] ext4: Allow rename even if link count is greater than EXT4_LINK_MAX for index directories
Date: Wed, 26 Aug 2009 17:07:25 +0530	[thread overview]
Message-ID: <1251286645-14439-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)

With EXT4_FEATURE_RO_COMPAT_DIR_NLINK we enable more than EXT4_LINK_MAX
sub directories. So we should not fail rename with too many links error
if EXT4_FEATURE_RO_COMPAT_DIR_NLINK feature is set.
