hi, ext2simg.c file was moved from android (system/extras) into e2fsprogs. however it seems that it cannot be compiled outside of android (it uses sparse/sparse.h). some distro used to build/package this utility (e.g. debian has it in android-tools-fsutils). what was the main reason why it was moved into e2fsprogs in the first place, given that it cannot be compiled (easily) outside of AOSP? Also, the commit that brought this file has the following reference: From AOSP commit: c1b7d19958dc3dbe53810811ea3dcc4f04f85c73 However I don't think this commit in AOSP. thanks!
