by Pino Toscano
When reading commands from a file, handle also Arg.Set parameters, so
they can be enabled as well.

[PATCH 00/16] btrfs: add support to btrfs scrub, balance, rescue and inspect
by Hu Tao
Hi,
This series adds new APIs to support btrfs scrub, balance, rescue
and inspect.
Some of them don't have tests because:
- btrfs_scrub and btrfs_balance completes too early before we can
test btrfs_scrub_cancel, btrfs_scrub_resume, btrfs_scrub_status,
btrfs_balance_pause, btrfs_balance_cancel, btrfs_balance_resume
and btrfs_balance_status.
- can't determine a valid logical address for test
btrfs_inspect_logical_resolve.
Thank you very much for review!
Regards,
Hu
Hu Tao (16):
New API: btrfs_scrub
New API: btrfs_scrub_cancel
New API: btrfs_scrub_resume
btrfs: replace "btrfs filesystem balance" with "btrfs balance"
New API: btrfs_balance_pause
New API: btrfs_balance_cancel
New API: btrfs_balance_resume
New API: btrfs_balance_status
New API: btrfs_scrub_status
New API: add btrfs_filesystem_defragment
New API: add btrfs_rescue_chunk_recover
New API: add btrfs_rescue_super_recover
New API: btrfs_inspect_rootid
New API: btrfs_inspect_subvolid_resolve
New API: btrfs_inspect_inode_resolve
New API: btrfs_inspect_logical_resolve

Pass to --commands-from-file the name of a file containing customization
commands in each line, as if they were specified as command line

[PATCH] daemon: readdir: fix invalid memory access on error
by Pino Toscano
If "strdup (d->d_name)" fails with "i" > 0, then both "p" and
"ret->guestfs_int_dirent_list_val" are non-null pointers, but the latter
is no more valid (since "p" is the new realloc'ed buffer). Hence, trying
to free both will access to invalid memory.
Make sure to free only one of them, "p" if not null or
"ret->guestfs_int_dirent_list_val" otherwise.

[PATCH] aarch64: launch: libvirt: As a workaround, pass -cpu parameter to qemu.
by Richard W.M. Jones
From: "Richard W.M. Jones" <rjones(a)redhat.com>
When libguestfs is running using TCG on aarch64, we need to pass the
-cpu cortex-a57 parameter to qemu. Libvirt doesn't let us do this,
complaining "Unable to find CPU definition".
As a temporary workaround only, use <qemu:commandline> to pass this
argument directly to qemu. When libvirt is fixed we can remove this
hack.
This is a workaround for libvirt bug RHBZ#1184411.
See:
https://www.redhat.com/archives/libvirt-users/2014-August/msg00043.html
