From: Omar Sandoval <osandov@xxxxxx>
Hi,
This series implements some support for space_cache=v2 in btrfs-progs.
In particular, this adds support for `btrfs check --clear-space-cache v2`,
proper printing of the free space tree flags for `btrfs inspect-internal
dump-super`, and better documentation.
We'd previously talked about always making btrfs-progs always invalidate
the free space tree when doing write operations, but I decided that this
should be an action explicitly requested by the user. It'd also be
unsafe if using a kernel without the free space tree valid bit support,
which is why I didn't implement a `btrfs check --invalidate-free-space-cache`
option. Doing the full clear is always safe.
Still missing is full read-write support, but this should hopefully
cover most btrfs-progs usage.
Thanks!
Omar Sandoval (6):
btrfs-progs: add the FREE_SPACE_TREE_VALID compat_ro bit definition
btrfs-progs: format FREE_SPACE_TREE{,_VALID} nicely in dump-super
btrfs-progs: add OPEN_CTREE_INVALIDATE_FST flag
btrfs-progs: add btrfs_clear_free_space_tree() from the kernel
btrfs-progs: implement btrfs check --clear-space-cache v2
btrfs-progs: document space_cache=v2 more thoroughly
