Hi, I tried building latest btrfs progs on CentOS 6, "./configure" failed with the error: checking for FIEMAP_EXTENT_SHARED defined in linux/fiemap.h... no configure: error: no definition of FIEMAP_EXTENT_SHARED found Any ideas what am I lacking in the system?
Your kernel is too old and its header doesn't support FIEMAP_EXTENT_SHARED flag for fiemap ioctl.
And since that flag is very important for tools like "btrfs filesystem du", for old kernel doesn't support EXTENT_SHARED flag, we have no choice but abort configuration.
Thanks, Qu
