[Cluster-devel] [PATCH v7 00/12] gfs2 iomap write support

[Andreas Gruenbacher <agruenba@redhat.com>]

Here's an update of my gfs2 iomap write patches, with support for
buffered writes as well as direct I/O reads and writes through iomap.


Significant changes since v6:

 * Switch to Christoph's patch for splitting out __generic_write_end and 
   put the inode-dirtying change in a separate commit.

 * Switch froma mandatory write_end operation to an optional
   page_write_end hook.

 * Add a patch to pass struct iomap_ops in struct iomap at the end for
   demonstration purposes.


Significant changes since v5:

 * Initial gfs2 specific cleanups split off and posted separately.

 * New patch for generic iomap inline data handling.

 * Iomap write_begin operation removed.


A 4.17 based version of the patches can be found here:

Thanks,
Andreas
