long standing bug (read "specification violation") where the server would send an invalid response when the client has cancelled an in-flight request. This was causing annoying spurious EINTR returns in linux. The fix comes with some related testing in QTEST. Other patches are code cleanup and improvements. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEtIKLr5QxQM7yo0kQcdTV5YIvc9YFAlp0OmMACgkQcdTV5YIv c9bM2w/+ORsH7ifYVoPZDwPdhLAVg8t4aU7ak7kWSOeuTZhE8WA6GL8T4rjnhZZ4 PbFZTye0fOsZZaT30sHUIwI/CGewvdx0kMJuX339XfwaWvsrF/8tHFA8QdreclVf YlLJwD2yZRujWPCU8k5D3hUfH2YD/w68b9Hv7K2hgsPw1Zoq7pLi/B2/BK/62G1d 35nFG97xDmcScSybrIeLwaCIKW/wgjHsWgUgAVMpgaSwtu/JTtEG5JYCZLGO6HVa p67zdVQbCKQcdPLLllcrnGdWlA4CGxCBe+WMQyL3eJ2VDEH6XTBX8DiLstIVlXfj vXb7vjlsYxE6rdeiMXRZWDGK+jZIePmDsI6ILlpyL0rEphuBnjEMljCxyBnOp7gS dMTFmhfP4mApaYxeENlpQ5noDeQ/Jr1c9YeeBh9UnZ7r16/m3f2/sEIh+6QTL7YD iR7ZG5LF0eP5SJKoZNV0i4123A5I7v1ekn5N5q6Kf4PMcY11507lxZksPhckdPgp FPhsJJ1JQzWMcfE1mKeiZXq5Cys4EUhUK6UrOFp6tO38H/3YMuYMAz25D46Xk3Zx qGuptCaov9uPi+5uqKuG3aJ9nMIMW9ZJdMSWo2+kb4EX4hMiOewjOJtaKA11QeS+ YoEr3szKtVnPUKsiqm+lhHL6ec5B8NQB7f8Hl88pkoLBGQzMaWU= =9T0i -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/gkurz/tags/for-upstream' into staging This series is mostly about 9p request cancellation.
