-EMSGSIZE (a) endpoint maxpacket size is zero; it is not usable
in the current interface altsetting.
(b) ISO packet is biger than endpoint maxpacket
(c) requested data transfer size is invalid (negative)
(b) ISO packet is larger than the endpoint maxpacket.
(c) requested data transfer length is invalid: negative
or too large for the host controller.
-ENOSPC This request would overcommit the usb bandwidth reserved
for periodic transfers (interrupt, isochronous).

/*
* Read/write a 16 bit word from flash address 'addr'.
*
* When the cpu is in little-endian mode it swizzles the address lines
* ('address coherency') so we need to undo the swizzling to ensure commands
* and the like end up on the correct flash address.
*
* To further complicate matters, due to the way the expansion bus controller
* handles 32 bit reads, the byte stream ABCD is stored on the flash as:
* D15 D0
* +---+---+
* | A | B | 0
* +---+---+
* | C | D | 2
* +---+---+
* This means that on LE systems each 16 bit word must be swapped. Note that
* this requires CONFIG_MTD_CFI_BE_BYTE_SWAP to be enabled to 'unswap' the CFI
* data and other flash commands which are always in D7-D0.

Version 1.39
------------
Defer close of a file handle slightly if pending writes depend on that file handle
Defer close of a file handle slightly if pending writes depend on that handle
(this reduces the EBADF bad file handle errors that can be logged under heavy
stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
Fix SFU style symlinks and mknod needed for servers which do not support the CIFS
Unix Extensions. Fix setfacl/getfacl on bigendian.
Fix SFU style symlinks and mknod needed for servers which do not support the
CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
dentries so files that the client sees as deleted but that later get created
on the server will be recognized. Add client side permission check on setattr.
