Message-ID: <cover.1767716314.git.dsterba@suse.com> (raw)

Collection of short clenups that improve code that's somehow performance
sensitive. The improvements are on instruction level or reduce stack
consumption.

David Sterba (12):
  btrfs: remove duplicate calculation of eb offset in btrfs_bin_search()
  btrfs: unify types for binary search variables
  btrfs: rename local variable for offset in folio
  btrfs: read eb folio index right before loops
  btrfs: use common eb range validation in
    read_extent_buffer_to_user_nofault()
  btrfs: lzo: inline read/write length helpers
  btrfs: zlib: drop redundant folio address variable
  btrfs: zlib: don't cache sectorsize in a local variable
  btrfs: zlib: remove local variable nr_dest_folios in
    zlib_compress_folios()
  btrfs: zstd: reuse total in and out parameters for calculations
  btrfs: zstd: don't cache sectorsize in a local variable
  btrfs: zstd: remove local variable nr_dest_folios in
    zstd_compress_folios()
