Btrfs: catch invalid free space trees

2016-10-03T16:52:14Z

There are two separate issues that can lead to corrupted free space trees. 1. The free space tree bitmaps had an endianness issue on big-endian systems which is fixed by an earlier patch in this series. 2. btrfs-progs before v4.7.3 modified filesystems without updating the free space tree. To catch both of these issues at once, we need to force the free space tree to be rebuilt. To do so, add a FREE_SPACE_TREE_VALID compat_ro bit. If the bit isn't set, we know that it was either produced by a broken big-endian kernel or may have been corrupted by btrfs-progs. This also provides us with a way to add rudimentary read-write support for the free space tree to btrfs-progs: it can just clear this bit and have the kernel rebuild the free space tree.

Btrfs: use the correct struct for BTRFS_IOC_LOGICAL_INO

2016-07-26T11:52:25Z

BTRFS_IOC_LOGICAL_INO takes a btrfs_ioctl_logical_ino_args as argument, not a btrfs_ioctl_ino_path_args. The lines were probably copy/pasted when the code was written. Since btrfs_ioctl_logical_ino_args and btrfs_ioctl_ino_path_args have the same size, the actual IOCTL definition here does not change. But, it makes the code less confusing for the reader.
