The primary intended use of this code is to converting freshly created zero-length files and empty directories. Note that the version of chattr in e2fsprogs 1.42.7 and earlier has a check that prevents the clearing of the extent flag. A simple patch which allows "chattr -e " to work will be checked into the e2fsprogs git repository. Signed-off-by: "Theodore Ts'o" --- Reading git-diff-tree failed
