Chris Ball	fcdc0929c6	Fix unused-but-set errors in gcc-4.6 gcc-4.6 (as shipped in Fedora) turns on -Wunused-but-set-variable by default, which breaks the build when combined with -Wall, e.g.: debug-tree.c: In function ‘print_extent_leaf’: debug-tree.c:45:13: error: variable ‘last_len’ set but not used [-Werror=unused-but-set-variable] debug-tree.c:44:13: error: variable ‘last’ set but not used [-Werror=unused-but-set-variable] debug-tree.c:41:21: error: variable ‘item’ set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors This patch fixes the errors by removing the unused variables.

Yan Zheng	088f78aeaa	Port extent buffer to btrfs-progs This patch ports extent buffer to btrfs-progs. extent_map.c contains a simplified extent map tree and functions that manipulate/manage extent buffer. extent state related codes are based on corresponding codes in kernel module, codes that manage extent buffer are from disk-io.c.	2008-01-04 10:36:26 -05:00
