Subject: [PATCH 0/3] Btrfs-progs: fix unaligned acces for ioctl search header
Date: Tue,  3 May 2016 18:12:34 +0200	[thread overview]
Message-ID: <cover.1462291729.git.dsterba@suse.com> (raw)

A user reports that some commands fail with SIGBUS on SPARC, due to unaligned
access. We should really use the helpers as the search header data are read
from a random position in the buffer that's returned from the TREE_SEARCH
ioctl.

David Sterba (3):
  btrfs-progs: kerncompat: introduce get_unaligned helpers
  btrfs-progs: add getters for ioctl search_header
  btrfs-progs: use ioctl search headers everywhere
