      Pull percpu fix from Dennis Zhou:
       "This contains a fix for sporadically failing atomic percpu
        allocations.
      
        I only caught it recently while I was reviewing a new series [1] and
        simultaneously saw reports by btrfs in xfstests [2] and [3].
      
        In v5.9, memcg accounting was extended to percpu done by adding a
        second type of chunk. I missed an interaction with the free page float
        count used to ensure we can support atomic allocations. If one type of
        chunk has no free pages, but the other has enough to satisfy the free
        page float requirement, we will not repopulate the free pages for the
        former type of chunk. This led to the sporadically failing atomic
        allocations"

      btrfs: zoned: move superblock logging zone location · 53b74fa9
      Naohiro Aota authored
      Moves the location of the superblock logging zones. The new locations of
      the logging zones are now determined based on fixed block addresses
      instead of on fixed zone numbers.
      
      The old placement method based on fixed zone numbers causes problems when
      one needs to inspect a file system image without access to the drive zone
      information. In such case, the super block locations cannot be reliably
      determined as the zone size is unknown. By locating the superblock logging
      zones using fixed addresses, we can scan a dumped file system image without
      the zone information since a super block copy will always be present at or
      after the fixed known locations.
      
      Introduce the following three pairs of zones containing fixed offset
      locations, regardless of the device zone size.
      
        - primary superblock: offset   0B (and the following zone)
        - first copy:         offset 512G (and the following zone)
        - Second copy:        offset   4T (4096G, and the following zone)
      
      If a logging zone is outside of the disk capacity, we do not record the
      superblock copy.
      
      The first copy position is much larger than for a non-zoned filesystem,
      which is at 64M.  This is to avoid overlapping with the log zones for
      the primary superblock. This higher location is arbitrary but allows
      supporting devices with very large zone sizes, plus some space around in
      between.
      
      Such large zone size is unrealistic and very unlikely to ever be seen in
      real devices. Currently, SMR disks have a zone size of 256MB, and we are
      expecting ZNS drives to be in the 1-4GB range, so this limit gives us
      room to breathe. For now, we only allow zone sizes up to 8GB. The
      maximum zone size that would still fit in the space is 256G.
      
      The fixed location addresses are somewhat arbitrary, with the intent of
      maintaining superblock reliability for smaller and larger devices, with
      the preference for the latter. For this reason, there are two superblocks
      under the first 1T. This should cover use cases for physical devices and
      for emulated/device-mapper devices.
      
      The superblock logging zones are reserved for superblock logging and
      never used for data or metadata blocks. Note that we only reserve the
      two zones per primary/copy actually used for superblock logging. We do
      not reserve the ranges of zones possibly containing superblocks with the
      largest supported zone size (0-16GB, 512G-528GB, 4096G-4112G).
      
      The zones containing the fixed location offsets used to store
      superblocks on a non-zoned volume are also reserved to avoid confusion.
