debugfs.c: do sparse copy when src is a sparse file Let debugfs do sparse copy when src is a sparse file, just like "cp --sparse=auto" * For the: #define IO_BUFSIZE 64*1024 this is a suggested value from gnu coreutils: http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=blob;f=src/ioblksize.h;h=1ae93255e7d0ccf0855208c7ae5888209997bf16;hb=HEAD * Use malloc() to allocate memory for the buffer since put 64K (or more) on the stack seems not a good idea.
