* fhandler.h (class fhandler_dev_raw): Add members devbufalloc and
devbufalign.
(class fhandler_dev_floppy): Remove member bytes_per_sector;
* fhandler_floppy.cc (bytes_per_sector): Define as devbufalign.
(fhandler_dev_floppy::open): Set devbufalign to a multiple of the
sector size and handle devbuf allocation and alignment in !O_DIRECT
case here. Change comment accordingly.
Call FSCTL_ALLOW_EXTENDED_DASD_IO for partitions as well.
(fhandler_dev_floppy::raw_write): Fix comment. Rewrite and fix
writing behaviour when application uses read and lseek.
(fhandler_dev_floppy::lseek): Use rounddown macro. Call
SetFilePointerEx rather than the old SetFilePointer.
(fhandler_dev_floppy::ioctl): Reformat switch. Call
IOCTL_DISK_UPDATE_PROPERTIES rather than IOCTL_DISK_UPDATE_DRIVE_SIZE
in BLKRRPART case. Support BLKIOMIN, BLKIOOPT, BLKPBSZGET and
BLKALIGNOFF.
* fhandler_raw.cc (fhandler_dev_raw::fhandler_dev_raw): Initialize
all devbuf-related members.
(fhandler_dev_raw::~fhandler_dev_raw): Delete devbufalloc rather than
devbuf.
(fhandler_dev_raw::open): Drop allocating devbuf.
(fhandler_dev_raw::dup): Allocate devbufalloc and set devbuf to support
new sector-aligned devbuf handling.
(fhandler_dev_raw::fixup_after_exec): Ditto.
* fhandler_tape.cc (fhandler_dev_tape::open): Ditto, set devbufalign
to 1.
* include/cygwin/fs.h (BLKIOMIN): Define.
(BLKIOOPT): Define.
(BLKALIGNOFF): Define.
(BLKPBSZGET): Define.
