The changes that were necessary are part of my github repo here:<br/> <a href="https://github.com/bacaldwell/lustre" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/bacaldwell/lustre</a></p> <p>Most of the changes were rebased upstream Linux patches, which are referenced in my commits. The specific issue mentioned in this ticket was addressed by this commit:<br/> <a href="https://github.com/bacaldwell/lustre/commit/663d8b7b2a6e42e0fba6b587f718732b1f756bd7#diff-8684eb9ba8f6ecca0e513931aa6bcd19R369" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/bacaldwell/lustre/commit/663d8b7b2a6e42e0fba6b587f718732b1f756bd7#diff-8684eb9ba8f6ecca0e513931aa6bcd19R369</a></p> <p>It needs quite a bit of cleanup, but hopefully will be a useful reference for this work.</p> <p>James Simmons (uja.ornl@yahoo.com) uploaded a new patch: <a href="http://review.whamcloud.com/14665" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/14665</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6260" title="more support for 3.16 linux kernel" class="issue-link" data-issue-key="LU-6260"><del>LU-6260</del></a> llite: add support for direct IO api changes<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 396f0bd17ad097a06cbac81db46461074d7d8a41</p> <p>Also in the 3.16 kernel we see the introduction of read_iter and write_iter. These later go on to replace the aio_write and aio_read functions. This change leads to the replacement of the generic_file_aio_XXX functions with the generic_file_XXX_iter functions in vvp_io.c.</p> <p>James Simmons (uja.ornl@yahoo.com) uploaded a new patch: <a href="http://review.whamcloud.com/15028" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/15028</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6260" title="more support for 3.16 linux kernel" class="issue-link" data-issue-key="LU-6260"><del>LU-6260</del></a> llite: add support for new iter functionality<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 302db32ec89b8a79343f01cebc309289ca6044a3</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/14665/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/14665/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6260" title="more support for 3.16 linux kernel" class="issue-link" data-issue-key="LU-6260"><del>LU-6260</del></a> llite: add support for direct IO api changes<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 98883bd3e2cc48a3a5674ce140ad74bece37df05</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/15028/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/15028/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6260" title="more support for 3.16 linux kernel" class="issue-link" data-issue-key="LU-6260"><del>LU-6260</del></a> llite: add support for new iter functionality<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 044503492c8e2e4cc519c34f282744d3d941a759</p> <p>So is it ok to mark this ticket as resolved now?</p> <p>Yes this work is finally done.</p> <p>Great!
