I'd suggest we add a new syscall, which implements the posix_fallocate() API as per the relevant specs. We can work the final details out with Ulrich and I'm sure that glibc's posix_fallocate() will start using the syscall if it is available. Actually, we should implement asmlinkage long sys_fallocate(int fd, loff_t offset, loff_t len); note: loff_t, not off_t. This probably means that we'll need to implement file_operations.fallocate(). It wouldn't surprise me if XFS was able to implement fallocate() too. - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
