Subject: [PATCH] linux-user: Use getcwd syscall directly
Date: Thu, 23 Jul 2020 12:27:13 +0200 [thread overview]
Message-ID: <mvmmu3qplvi.fsf@suse.de> (raw)
The glibc getcwd function returns different errors than the getcwd
syscall, which triggers an assertion failure in the glibc getcwd function
when running under the emulation.
