many places.  The notable patch series are:
 
 - nilfs2 folio conversion from Matthew Wilcox in "nilfs2: Folio
   conversions for file paths".
 
 - Additional nilfs2 folio conversion from Ryusuke Konishi in "nilfs2:
   Folio conversions for directory paths".
 
 - IA64 remnant removal in Heiko Carstens's "Remove unused code after
   IA-64 removal".
 
 - Arnd Bergmann has enabled the -Wmissing-prototypes warning everywhere
   in "Treewide: enable -Wmissing-prototypes".  This had some followup
   fixes:
 
   - Nathan Chancellor has cleaned up the hexagon build in the series
     "hexagon: Fix up instances of -Wmissing-prototypes".
 
   - Nathan also addressed some s390 warnings in "s390: A couple of
     fixes for -Wmissing-prototypes".
 
   - Arnd Bergmann addresses the same warnings for MIPS in his series
     "mips: address -Wmissing-prototypes warnings".
 
 - Baoquan He has made kexec_file operate in a top-down-fitting manner
   similar to kexec_load in the series "kexec_file: Load kernel at top of
   system RAM if required"
 
 - Baoquan He has also added the self-explanatory "kexec_file: print out
   debugging message if required".
 
 - Some checkstack maintenance work from Tiezhu Yang in the series
   "Modify some code about checkstack".
 
 - Douglas Anderson has disentangled the watchdog code's logging when
   multiple reports are occurring simultaneously.  The series is "watchdog:
   Better handling of concurrent lockups".
 
 - Yuntao Wang has contributed some maintenance work on the crash code in
   "crash: Some cleanups and fixes".

-----------------
=================== =========================================================
errors=%s Specify whether squashfs errors trigger a kernel panic
or not
========== =============================================
continue errors don't trigger a panic (default)
panic trigger a panic when errors are encountered,
similar to several other filesystems (e.g.
btrfs, ext4, f2fs, GFS2, jfs, ntfs, ubifs)
This allows a kernel dump to be saved,
useful for analyzing and debugging the
corruption.
========== =============================================
threads=%s Select the decompression mode or the number of threads
If SQUASHFS_CHOICE_DECOMP_BY_MOUNT is set:
========== =============================================
single use single-threaded decompression (default)
Only one block (data or metadata) can be
decompressed at any one time. This limits
CPU and memory usage to a minimum, but it
also gives poor performance on parallel I/O
workloads when using multiple CPU machines
due to waiting on decompressor availability.
multi use up to two parallel decompressors per core
If you have a parallel I/O workload and your
system has enough memory, using this option
may improve overall I/O performance. It
dynamically allocates decompressors on a
demand basis.
percpu use a maximum of one decompressor per core
It uses percpu variables to ensure
decompression is load-balanced across the
cores.
1|2|3|... configure the number of threads used for
decompression
The upper limit is num_online_cpus() * 2.
========== =============================================
If SQUASHFS_CHOICE_DECOMP_BY_MOUNT is **not** set and
SQUASHFS_DECOMP_MULTI, SQUASHFS_MOUNT_DECOMP_THREADS are
both set:
