Subject: [PATCH] Doc fix: ext2 can only have 32,000 subdirs, not 32,768.
Date: Mon, 18 May 2009 12:13:51 -0700 [thread overview]
Message-ID: <63a2e74f0905181213r54a2d8b2tb7dcecd177d474c2@mail.gmail.com> (raw)
ext2.txt says that dirs can have 32,768 subdirs, but the actual value
of EXT2_LINK_MAX is 32000.
ext3 is the same, but the doc does not mention it. One of ext4's
features is to "fix 32000 subdirectory limit".
