Chris Mason 1b74adf90b Change btrfs_map_block to return a structure with mappings for all stripes 2008-04-09 16:28:12 -04:00
Chris Mason a37e1e7204 Recow all roots at the end of mkfs 
The mkfs code bootstraps the filesystem on a single device.  Once
the raid block groups are setup, it needs to recow all of the blocks so
that each tree is properly allocated.

Alex Chiang 857e9a2a63 btrfs-progs: Fix printf format casting errors 
We get lots of warnings of the flavor:

utils.c:441: warning: format '%Lu' expects type 'long long unsigned int' but argument 2 has type 'u64'

And thanks to -Werror, the build fails. Clean up these printfs
by properly casting the arg to the format specified.

Yan ece29db279 Call btrfs_cow_block while lowering tree level. 
When freeing root block of a tree,  btrfs_free_extent' parameter
'ref_generation' is from root block itseft.  When freeing non-root
block,  'ref_generation' is from its parent. so when converting a
non-root block to root block, we must guarantee its generation is
equal to its parent's generation.

Yan 281c171293 Remove kernel-space header in btrfs-progs 
When porting ctree.c in btrfs kernel module to btrfs-progs, I forgot

system.
