2019-09-09btrfs: move math functions to misc.hDavid Sterba1-1/+1

2019-09-09btrfs: rename the btrfs_calc_*_metadata_size helpersJosef Bacik1-2/+2
btrfs_calc_trunc_metadata_size differs from trans_metadata_size in that it doesn't take into account any splitting at the levels, because truncate will never split nodes. However truncate _and_ changing will never split nodes, so rename btrfs_calc_trunc_metadata_size to btrfs_calc_metadata_size. Also btrfs_calc_trans_metadata_size is purely for inserting items, so rename this to btrfs_calc_insert_metadata_size. Making these clearer will help when I start using them differently in upcoming patches.

2019-09-09btrfs: unexport the temporary exported functionsJosef Bacik1-14/+14
These were renamed and exported to facilitate logical migration of different code chunks into block-group.c. Now that all the users are in one file go ahead and rename them back, move the code around, and make them static.
