Message-ID: <63a2e74f0905181213r54a2d8b2tb7dcecd177d474c2@mail.gmail.com> Date: Mon, 18 May 2009 12:13:51 -0700 From: Michael Shields <mshields@...gle.com> To: rdunlap@...otime.net, linux-ext4@...r.kernel.org Cc: linux-kernel@...r.kernel.org, trivial@...nel.org Subject: [PATCH] Doc fix: ext2 can only have 32,000 subdirs, not 32,768. 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". --- linux-2.6.29.3/Documentation/filesystems/ext2.txt.orig 2009-05-08 15:47:21.000000000 -0700 +++ linux-2.6.29.3/Documentation/filesystems/ext2.txt 2009-05-18 12:03:58.000000000 -0700 @@ -322,7 +322,7 @@ an upper limit on the block size imposed so 8kB blocks are only allowed on Alpha systems (and other architectures which support larger pages). -There is an upper limit of 32768 subdirectories in a single directory. +There is an upper limit of 32000 subdirectories in a single directory.
