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
