<p class="MsoNormal" style="margin-bottom:12.0pt">These are the only callers for removexattr and only _posix_remove_xattr has the potential to do removexattr as posix_removexattr already makes sure that it is not gfid/volume-id. And surprise surprise _posix_remove_xattr
happens only from healing code of afr/ec. And this can only happen if the source brick doesn't have gfid, which doesn't seem to match with the situation you explained.
