I see the following:
WARNING: Missing a blank line after declarations
#1921: FILE: fs/cifs/smb2ops.c:4684:
+ struct folio *folio;
+ XA_STATE(xas, buffer, 0);
but XA_STATE() technically *is* a declaration.
Should checkpatch treat it as such?

XA_STATE() and XA_STATE_ORDER macro uses are declarations.
Add them to the declaration macro list to avoid suggesting a blank line
after declarations when used.
