Subject: [PATCH v3 0/5] linux-user: Passthrough MADV_DONTNEED for certain file mappings
Date: Tue, 6 Sep 2022 02:08:34 +0200 [thread overview]
Message-ID: <20220906000839.1672934-1-iii@linux.ibm.com> (raw)
Hi,
This series is made of patches from [1]. I've added a test and noticed
that madvise(MADV_DONTNEED) was broken on alpha, fixing which required
adding per-arch MADV_* definitions. This in turn affected the strace
patch, so it made sense to make a series out of the results.
Patch 1 adds MADV_* constants for all architectures.
Patch 2 fixes the alpha bug.
Patch 3 adds madvise() support to strace.
Patch 4 adds MADV_DONTNEED support for file mappings.
Patch 5 adds a test.
Best regards,
Ilya
