[PATCH 0/3] Send: minor cleanups, add RO checks
First two patches are trivial cleanups that I''ve spotted while reading send.c,
can be applied independently.
The third patch contains the important bits, safety checks that the subvolumes
involved in send do not accidentally lose the RO status. I haven''t seen this
documented anywhere that this is mandatory, implied from how I assume send
works. Please let me know if this is

This patch adds creation-time to the snapshot list display,
which would help user to better manage the snapshots when
number of snapshots grow substantially. This patch is developed
and on top of the send/receive btrfs and btrfs-progs repo at

2. Clean up the existing build process, to get rid of tools/build and

3. Make the bzImage payload an ELF file. The bootloader can extract
this as a naked ELF file by skipping over boot_params.setup_sects worth
of 16-bit setup code.
