[PATCH 0/6] Cleanups and W=2 warning fixes

[David Sterba <dsterba@suse.com>]

We have a clean run of 'make W='1 with gcc 13, there are some
interesting warnings to fix with level 2 and even 3. We can't enable the
warning flags by defualt due to reports from generic code.

This short series removes shadowed variables, adds const and removes
an unused macro. There are still some shadow variables to fix but the
remaining cases are with 'ret' variables so I skipped it for now.

David Sterba (6):
  btrfs: remove duplicate name variable declarations
  btrfs: rename macro local variables that clash with other variables
  btrfs: use for-local variabls that shadow function variables
  btrfs: remove unused define EXTENT_SIZE_PER_ITEM
  btrfs: keep const whene returnin value from get_unaligned_le8()
  btrfs: constify parameters of write_eb_member() and its users
