commit 5f6f120984969e7f0e294b77a8851b2a0b2642ab Author: Mark Geisert <[email protected]> AuthorDate: Thu Mar 5 02:52:33 2026 -0800 Commit: Corinna Vinschen <[email protected]> CommitDate: Wed Mar 11 15:59:27 2026 +0100 Cygwin: Change mappings of Windows ERROR*QUOTA* While testing the new rlimit implementation, it was noticed fork() returns an EIO error on hitting the process count limit. Per POSIX, the error should be EAGAIN. This patch makes the change. Along the way it was noticed Windows ERROR_DISK_QUOTA_EXCEEDED was not being mapped to any POSIX error. This patch changes the mapping to EFBIG.
