[NILFS users] NILFS 2.0.15 released

[Ryusuke Konishi]

Hi everyone,

I have released nilfs-2.0.15 standalone package, which includes
several bug fixes including hang problem after write failures.  This
also includes a change to improve read performance on some fast
drives.

Here is a summary of changes from the previous version:

* enable sync_page method; this adds a missing sync_page method which
  unplugs bio requests during lock retries on pages. This will improve
  read performance of nilfs.
* fix bh leak in nilfs_cpfile_delete_checkpoints function
* fix disorder in checkpoint count on error during deleting
  checkpoints
* fix hang problem of log writer which occurs after write failures
* remove unlikely directive causing mis-conversion of error code
* fix lockdep warning between regular file and inode file
* fix incorrect KERN_CRIT messages in case of write failures
* correct display of sequence counter printed when request has
  completed
* separate debug message related to transaction from ones for segment


The updated package is available at http://www.nilfs.org/en/download.html.

Thanks,
Ryusuke Konishi
