From 5b6a3a2b4a5f071d170f8122038dd647a84810a8 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Thu, 13 Sep 2007 16:33:54 -0700 Subject: ocfs2: Write support for directories with inline data Create all new directories with OCFS2_INLINE_DATA_FL and the inline data bytes formatted as an empty directory. Inode size field reflects the actual amount of inline data available, which makes searching for dirent space very similar to the regular directory search. Inline-data directories are automatically pushed out to extents on any insert request which is too large for the available space.
