18fe6a23e3 NFS: Set FATTR4_WORD0_TYPE for . and .. entries
The current code worked okay for getdents(), but getdents64() expects
the d_type field to get filled out properly in the stat structure.
Setting this field fixes xfstests generic/401.

800222f80f nfsd4: const-ify nfsd4_ops
nfsd4_ops contains function pointers, and marking it as constant avoids

0becc1181c sunrpc: move pc_count out of struct svc_procinfo
pc_count is the only writeable memeber of struct svc_procinfo, which is
a good candidate to be const-ified as it contains function pointers.

This patch moves it into out out struct svc_procinfo, and into a
separate writable array that is pointed to by struct svc_version.

72edc37a2c nfsd4: properly type op_func callbacks
Pass union nfsd4_op_u to the op_func callbacks instead of using unsafe
function pointer casts.

It also adds two missing structures to struct nfsd4_op.u to facilitate
this.

3a00be1923 RTC for 4.13
Subsystem:
  - expose non volatile RAM using nvmem instead of open coding in many
  drivers. Unfortunately, this option has to be enabled by default to not
  break existing users.
  - rtctest can now test for cutoff dates, showing when an RTC will start
  failing to properly save time and date.
  - new RTC registration functions to remove race conditions in drivers
 
 Newly supported RTCs:
  - Broadcom STB wake-timer
  - Epson RX8130CE
  - Maxim IC DS1308
  - STMicroelectronics STM32H7
 
 Drivers:
  - ds1307: use regmap, use nvmem, more cleanups
  - ds3232: temperature reading support
  - gemini: renamed to ftrtc010
  - m41t80: use CCF to expose the clock
  - rv8803: use nvmem
  - s3c: many cleanups

Pull RTC updates from Alexandre Belloni:
 "Here is the pull-request for the RTC subsystem for 4.13.

  Subsystem:

   - expose non volatile RAM using nvmem instead of open coding in many
     drivers. Unfortunately, this option has to be enabled by default to
     not break existing users.

   - rtctest can now test for cutoff dates, showing when an RTC will
     start failing to properly save time and date.

   - new RTC registration functions to remove race conditions in drivers

  Newly supported RTCs:

   - Broadcom STB wake-timer

   - Epson RX8130CE

   - Maxim IC DS1308

   - STMicroelectronics STM32H7

  Drivers:

   - ds1307: use regmap, use nvmem, more cleanups

   - ds3232: temperature reading support

   - gemini: renamed to ftrtc010

   - m41t80: use CCF to expose the clock

   - rv8803: use nvmem

   - s3c: many cleanups

   - st-lpc: fix y2106 bug"

b5e16170f5 MTD updates for v4.13-rc1:
General updates
 
  * Cleanups and additional flash support for "dataflash" driver
  * new driver for mchp23k256 SPI SRAM device
  * improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE)
  * refactor and improve "sub-partition" handling with TRX partition
    parser; partitions can now be created as sub-partitions of another
    partition
 
 SPI NOR updates, from Cyrille Pitchen and Marek Vasut:
  * introduce support to the SPI 1-2-2 and 1-4-4 protocols.
  * introduce support to the Double Data Rate (DDR) mode.
  * introduce support to the Octo SPI protocols.
  * add support to new memory parts for Spansion, Macronix and Winbond.
  * add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers.
  * clean up the st_spi_fsm driver.
 
 NAND updates, from Boris Brezillon:
 
  * addition of on-die ECC support to Micron driver
  * addition of helpers to help drivers choose most appropriate ECC
    settings
  * deletion of dead-code (cached programming and ->errstat() hook)
  * make sure drivers that do not support the SET/GET FEATURES command
    return ENOTSUPP use a dummy ->set/get_features implementation
    returning -ENOTSUPP (required for Micron on-die ECC)
  * change the semantic of ecc->write_page() for drivers setting the
    NAND_ECC_CUSTOM_PAGE_ACCESS flag
  * support exiting 'GET STATUS' command in default ->cmdfunc()
    implementations
  * change the prototype of ->setup_data_interface()
 
  A bunch of driver related changes:
 
  * various cleanup, fixes and improvements of the MTK driver
  * OMAP DT bindings fixes
  * support for ->setup_data_interface() in the fsmc driver
  * support for imx7 in the gpmi driver
  * finalization of the denali driver rework (thanks to Masahiro for the
    work he's done on this driver)

7d84120b5b Documentation: ABI: mtd: describe "offset" more precisely
So far Linux supported only two levels of MTD devices so we didn't need
a very precise description for this sysfs file. With commit
97519dc52b ("mtd: partitions: add support for subpartitions") there
is support for a tree structure so we should have more precise
description. Using "parent" and "flash device" makes it more accurate.

4d9bcaddac ext2: Fix memory leak when truncate races ext2_get_blocks
Buffer heads referencing indirect blocks may not be released if the file
is truncated at the right time. This happens because ext2_get_branch()
returns NULL when it finds the whole chain of indirect blocks already
set, and when truncate alters the chain this value of NULL is
treated as the address of the last head to be released. Handle this in the
same way as it's done after the got_it label.
