Re: [PATCH v3 0/5] MR3103: server: Create and use a desktop shared mapping for GetCursorPos.

v2: Use pointer to const when possible for the desktop_shm_t, make it writable only within SHARED_WRITE_BEGIN/END. Remove the recursive sequence number and the related asserts. I rebased and pushed the update to quickly apparently, Gitlab UI messed it up, the range-diff is 8bf8fb91603...8cd46e3de73. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3103#note_41246

Instead of creating a new directory object, how about we just make the desktop object itself a namespace and implement `object_ops::lookup_name`? Instead of WindowsStations\__wine_desktop_mappings\WinSta0\Default , we'd open WindowsStations\WinSta0\Default\__wine_desktop_mapping . -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3103#note_41245

I feel that is a bit overkill for a single application, which is using the lock in an invalid way anyway. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3504#note_41229

That makes some amount of sense (not that I know why the application thinks it needs to mess with lock state manually, but, well, It Happens).

@zfigura I think this is unfortunately a case of the application looking at the internal state of something that's supposed to be opaque. The application here is specifically creating a `SRWLOCK`, manipulating its internal state not through the APIs, then calling `ReleaseSRWLockExclusive` and inspecting the result. And if the result is different from what it expects, it opens a KeyedEvent for `"\\KernelObjects\\CritSecOutOfMemoryEvent"`, and waits on it in a loop. I can't tell you why it's doing that. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3504#note_41224

I don't think this makes sense if we aren't representing lock state the same way. > This fixes a dead lock which prevents WeCom from starting up. How does this deadlock occur? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/3504#note_41223
