From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mx2.suse.de ([195.135.220.15]:36237 "EHLO mx2.suse.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751510AbbJPQvS (ORCPT ); Fri, 16 Oct 2015 12:51:18 -0400 From: David Sterba To: linux-btrfs@vger.kernel.org Cc: David Sterba , clm@fb.com Subject: [PULL][PATCH 0/2 v2] Balance filters: stripes, enhanced limit Date: Fri, 16 Oct 2015 18:50:05 +0200 Message-Id: MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Sender: linux-btrfs-owner@vger.kernel.org List-ID: Changelog (v2): * the limit_min logic was wrong and did not work, all other filters are locally applied to the processed chunk, but for the limit_min we need to count all filters first and then decide if we want to rebalance or not Update to balance filters, intended for 4.4: * new 'stripes=' - process only stripes that cross given number of devices, specified by a range * updated 'limit=' - previously a single number was accepted, it's a range so now we can specify a minimum number of chunks to process There will be more documentation about the use in the btrfs-progs patches, the kernel side just applies the ranges. The update to 'limit' is backward compatible, reuses the previous struct member. Need the v2 btrfs-progs patchset. Note to merging: there's a missing patch that actuall adds both filter flags to the mask, however this patch[1] will supposedly be merged to 4.3-rc6. Current integration is based on 4.3-rc5 so I can't send a branch containing that without pulling unrelated patches. I'll send the patch independently so you can decide how to apply it once your first 4.4 pull request gets merged.
