Subject: [PATCH v5 0/6] erofs: cleanup of xattr handling
Date:   Thu,  1 Jun 2023 10:43:41 +0800

changes since v4:
- patch 1: make conversions from erofs_read_metabuf() in xattr.c
  to "erofs_init_metabuf() + erofs_bread()" a separate patch
- patch 6: add "bool copy" function parameter to erofs_xattr_body(), and
  thus make erofs_xattr_namematch() and erofs_xattr_copy() inlined
  inside erofs_xattr_body()

changes since v3:
- patch 1: make a unified erofs_xattr_iter_fixup() API with newly
  introduced "bool nospan" argument; call erofs_init_metabuf() and
  erofs_bread() separately instead of erofs_read_metabuf()
- patch 2: avoid duplicated strlen() calculation in erofs_getxattr(); no
  need zeroing other fields when initializing 'struct erofs_xattr_iter'
- patch 4: don't explode 'struct erofs_xattr_iter' with inode/getxattr
  fields; instead pass inode/getxattr parameters through function
  parameters of erofs_iter_[inline|shared]_xattr()
- patch 5: don't explode 'struct erofs_xattr_iter' with remaining field;
  instead  calculate and check the remaining inside
  erofs_iter_inline_xattr()

changes since v2:
- rebase to v6.4-rc2
- passes xattr tests (erofs/019,020,021) of erofs-utils [1]
