If anyone has any objections, please let me know. ------------------ From: Chao Yu [ Upstream commit 186e7d71534df4589405925caca5597af7626c12 ] Previously, we account reserved blocks and compressed blocks into @compr_blocks, then, f2fs_i_compr_blocks_update(,compr_blocks) will update i_compr_blocks incorrectly, fix it. Meanwhile, for the case all blocks in cluster were reserved, fix to update dn->ofs_in_node correctly.
