From 4fed598a49c014cbc563179b25f2a4b8565e2a50 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sun, 12 Jul 2009 11:13:55 +0900 Subject: fs/Kconfig: move nilfs2 out fs/Kconfig file was split into individual fs/*/Kconfig files before nilfs was merged. I've found the current config entry of nilfs is tainting the work. Sorry, I didn't notice. This fixes the violation.

In addition to versioning capability of the entire + file system, users can even restore files mistakenly overwritten or + destroyed just a few seconds ago.

Users can + select significant versions among continuously created checkpoints, + and can change them into snapshots which will be preserved for long + periods until they are changed back to checkpoints. Each + snapshot is mountable as a read-only file system concurrently with + its writable mount, and this feature is convenient for online backup. + + Some features including atime, extended attributes, and POSIX ACLs, + are not supported yet. + + To compile this file system support as a module, choose M here: the + module will be called nilfs2.
