Subject: [PATCH 0/4] linux-user: shmat/shmdt improvements
Date: Sun, 20 Aug 2023 13:44:04 -0700	[thread overview]
Message-ID: <20230820204408.327348-1-richard.henderson@linaro.org> (raw)

A couple of points I noticed with bsd-user copying linux-user:

(1) Make sure to remap memory for reserved_va
(2) Use something better than an array for tracking shmat.
