      Enable '-Werror' by default for all kernel builds · 3fe617cc

      ... but make it a config option so that broken environments can disable
      it when required.
      We really should always have a clean build, and will disable specific
      over-eager warnings as required, if we can't fix them.  But while I
      fairly religiously enforce that in my own tree, it doesn't get enforced
      by various build robots that don't necessarily report warnings.
      So this just makes '-Werror' a default compiler flag, but allows people
      to disable it for their configuration if they have some particular
      Occasionally, new compiler versions end up enabling new warnings, and it
      can take a while before we have them fixed (or the warnings disabled if
      that is what it takes), so the config option allows for that situation.
      Hopefully this will mean that I get fewer pull requests that have new
      warnings that were not noticed by various automation we have in place.
      Knock wood.

      Pull f2fs updates from Jaegeuk Kim:
       "In this cycle, we've addressed some performance issues such as lock
        contention, misbehaving compress_cache, allowing extent_cache for
        compressed files, and new sysfs to adjust ra_size for fadvise.
        In order to diagnose the performance issues quickly, we also added an
        iostat which shows the IO latencies periodically.
        On the stability side, we've found two memory leakage cases in the
        error path in compression flow. And, we've also fixed various corner
        cases in fiemap, quota, checkpoint=disable, zstd, and so on.
         - avoid long checkpoint latency by releasing nat_tree_lock
         - collect and show iostats periodically
         - support extent_cache for compressed files
         - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
         - report f2fs GC status via sysfs
         - add discard_unit=%s in mount option to handle zoned device
        Bug fixes:
         - fix two memory leakages when an error happens in the compressed IO flow
         - fix commpress_cache to get the right LBA
         - fix fiemap to deal with compressed case correctly
         - fix wrong EIO returns due to SBI_NEED_FSCK
         - fix missing writes when enabling checkpoint back
         - fix quota deadlock
         - fix zstd level mount option
        In addition to the above major updates, we've cleaned up several code
        paths such as dio, unnecessary operations, debugfs/f2fs/status, sanity
        check, and typos"
