    Subject[PATCH 0/8] shmem,tmpfs: general maintenance
    And here is a series of patches based on v6.6-rc3: mostly just cosmetic
    mods in mm/shmem.c, but the last two enforcing the "size=" limit better.
    8/8 goes into percpu counter territory, and could stand alone: I'll add
    some more Cc's on that one.

    Applies to any v6.6-rc so far, and to next-20230929 and to
    mm-everything-2023-09-29-23-51: hah, there's now an 09-30-01-16,
    I haven't tried it yet, but this should be good on that too.

    1/8 shmem: shrink shmem_inode_info: dir_offsets in a union
    2/8 shmem: remove vma arg from shmem_get_folio_gfp()
    3/8 shmem: factor shmem_falloc_wait() out of shmem_fault()
    4/8 shmem: trivial tidyups, removing extra blank lines, etc
    5/8 shmem: shmem_acct_blocks() and shmem_inode_acct_blocks()
    6/8 shmem: move memcg charge out of shmem_add_to_page_cache()
    7/8 shmem: _add_to_page_cache() before shmem_inode_acct_blocks()
    8/8 shmem,percpu_counter: add _limited_add(fbc, limit, amount)
