bit 0 = Enable XRUN/jiffies debug messages
bit 1 = Show stack trace at XRUN / jiffies check
bit 2 = Enable additional jiffies check
+ bit 3 = Log hwptr update at each period interrupt
+ bit 4 = Log hwptr update at each snd_pcm_update_hw_ptr()
When the bit 0 is set, the driver will show the messages to
kernel log when an xrun is detected. The debug message is
buggy) hardware that doesn't give smooth pointer updates.
This feature is enabled via the bit 2.
+ Bits 3 and 4 are for logging the hwptr records. Note that
+ these will give flood of kernel messages.

- help
- NILFS2 is a log-structured file system (LFS) supporting continuous
- snapshotting. In addition to versioning capability of the entire
- file system, users can even restore files mistakenly overwritten or
- destroyed just a few seconds ago. Since this file system can keep
- consistency like conventional LFS, it achieves quick recovery after
- system crashes.
-
- NILFS2 creates a number of checkpoints every few seconds or per
- synchronous write basis (unless there is no change). 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. If unsure, say N.

+ select CRC32
+ help
+ NILFS2 is a log-structured file system (LFS) supporting continuous
+ snapshotting. In addition to versioning capability of the entire
+ file system, users can even restore files mistakenly overwritten or
+ destroyed just a few seconds ago. Since this file system can keep
+ consistency like conventional LFS, it achieves quick recovery after
+ system crashes.
+
+ NILFS2 creates a number of checkpoints every few seconds or per
+ synchronous write basis (unless there is no change). 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. If unsure, say N.
