Hello, Here is a small series which fixes an issue that got reported internally to Suse and which affects devices whose size is not multiple of sectorsize. More information can be found in the changelog for patch 2 The first patch in the series re-implements the btrfs_device_total_bytes getter/setters manually so that we can add a WARN_ON to catch future offenders. I haven't implemented all 4 function that the macros do since we only ever use the getter and setter. The second patch ensures that all the values passed to the setter are rounded down to a multiple of sectorsize. I also have an xfstest patch which passes after this series is applied. Changes since v1: * Moved some of the text from previous cover letter, into patch 2 to make explanation of the bug more coherent. * The first patch now only implements getter/setter while the 2nd patch adds the WARN_ON Nikolay Borisov (2): btrfs: Manually implement device_total_bytes getter/setter btrfs: Round down values which are written for total_bytes_size fs/btrfs/ctree.h | 21 ++++++++++++++++++++- fs/btrfs/volumes.c | 18 +++++++++++++----- 2 files changed, 33 insertions(+), 6 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
