* btrfs-progs: Add simple python front end to the search ioctlChris Mason2014-12-04
This is a starting point for a debugfs style python interface using the search ioctl. For now it can only do one thing, which is to print out all the extents in a file and calculate the compression ratio. Over time it will grow more features, especially for the kinds of things we might run btrfs-debug-tree to find out. Expect the usage and output to change dramatically over time (don't hard code to it). Signed-off-by: Chris Mason <clm@fb.com> Signed-off-by: David Sterba <dsterba@suse.cz>
