* btrfs-progs: per-thread, per-call pretty bufferZach Brown2013-08-09
| | | | | | | | | | | | | | | | | We don't need callers to manage string storage for each pretty_sizes() call. We can use a macro to have per-thread and per-call static storage so that pretty_sizes() can be used as many times as needed in printf() arguments without requiring a bunch of supporting variables. This lets us have a natural interface at the cost of requiring __thread and TLS from gcc and a small amount of static storage. This seems better than the current code or doing something with illegible format specifier macros.

* btrfs-progs: standardize tool source filenamesEric Sandeen2013-04-24
For any btrfs-$FOO executable, rename the main source file from $FOO.c to to btrfs-$FOO.c This makes it slightly more obvious what's building what, and allows us to write a default rule in the Makefile for these tools. (also add btrfs-calc-size to the list of objects to remove on make clean) Signed-off-by: Eric Sandeen <sandeen@redhat.com>
