Hi Jinoh, Sorry for the delay. The patch seems a bit risky for code freeze, but it fixes a regression, so I'm not sure. Anyway, I have a few comments bellow. On 1/4/22 11:08, Jinoh Kang wrote:

Why do you call alloc_pseudo_fd() here instead of named_pipe_device_lookup_name, where you alloc dir object? Also, it could use allow_fd_caching(). Thanks, Jacek

It's certainly possible to reuse the struct, but I suppose making the two structs separate would help check for potential object type confusion.

I actually borrowed that part from server/object.c. Puzzled I was at first, but I guessed there must be some legit reason as to why things were done that way, presumably for compatibility with older compilers. (Apparently GCC 4.x compilation problems on Bugzilla were recently acknowledged as legitimate and fixed). If this is not (or no longer) the case, perhaps we can modify the old code too?

named_pipe_device_lookup_name lacks the options parameter.
Also, it could use allow_fd_caching().
Thanks!

SUCCEEDED() macro is meant for HRESULT. It's not really needed here, I think that those two branches can be simplified to: if (status == STATUS_SUCCESS) { WaitForSingleObject(event, INFINITE); status = iosb.Status; } Thanks, Jacek
