When trying to move my root to a btrfs filesystem, I found a missing feature (or a bug). It's not possible to create device files. To reproduce, run this on a btrfs filesystem: mknod test c 1 1 result: mknod: `test': Operation not permitted Frank

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.

...in the btrfs O_DIRECT code, add a migrate_page operation to avoid metadata corruption as btree pages go through migration, and fix up our NFS support. Otherwise we have assorted correctness fixes, many of which were kicked out by xfsqa. -chris Josef Bacik (11) commits (+241/-54): Btrfs: make btrfs_add_nondir take parent inode as an argument (+16/-22) Btrfs: fix typo in fallocate to make it honor actual size (+5/-4) Btrfs: hold i_mutex when calling btrfs_log_dentry_safe (+7/-0) Btrfs: setup blank root and fs_info for mount time (+33/-7) Btrfs: make sure new inode size is ok in fallocate...
