fchdir, and fchown to - produce EBADF - -the workaround/fallback code for supporting O_PATH file descriptors -when the kernel lacks support for performing these operations on them -caused EBADF to get replaced by ENOENT (due to missing entry in -/proc/self/fd). this is unlikely to affect real-world code (calls that -might yield EBADF are generally unsafe, especially in library code) -but it was breaking some test cases. - -the fix I've applied is something of a tradeoff: it adds one syscall -to these operations on kernels where the workaround is needed. the -alternative would be to catch ENOENT from the /proc lookup and -translate it to EBADF, but I want to avoid doing that in the interest -of not touching/depending on /proc at all in these functions as long -as the kernel correctly supports the operations. this is following the -general principle of isolating hacks to code paths that are taken on -broken systems, and keeping the code for correct systems completely -hack-free.
