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.

Richard Henderson (4):
linux-user: Move shmat and shmdt implementations to mmap.c
linux-user: Use WITH_MMAP_LOCK_GUARD in target_{shmat,shmdt}
linux-user: Fix shmdt
linux-user: Track shm regions with an interval tree
linux-user/user-mmap.h | 4 +
linux-user/mmap.c | 168 +++++++++++++++++++++++++++++++++++++++++
