Hello,
The test case in previous mail doesn't work due to changes recently
pushed out. Here is the new test case.
Regards

#include <sys/types.h>

int main(int argc, char *argv[])
{

int ret;
char buf[8192];
fd = open(argv[1], O_RDWR | O_CREAT | O_EXCL, 0644);
if (fd < 0) {

exit(1);
}
/* create inline extent */
ret = pwrite(fd, buf, 1024 * 6 - 1, 4096);
if (ret < 0) {

exit(1);
}
/* disable packing of data */
ret = pwrite(fd, buf, 4096, 32768);
if (ret < 0) {
perror("write");
exit(1);
}
/* drop file extents in range 0 ~ 8192 */
ret = pwrite(fd, buf, 8192, 0);
if (ret < 0) {
perror("write");
exit(1);
}
close(fd);
return 0;
}
