Subject: [BUGFIX PATCH v2 0/5] selftests: Fixes for 32bit arch
Date: Mon, 21 Oct 2019 17:27:58 +0900	[thread overview]
Message-ID: <157164647813.17692.3834082082658965225.stgit@devnote2> (raw)

Hi,

Here are the 2nd version of kselftest fixes some on 32bit arch
(e.g. arm). In this version, I updated [1/5] to make va_max 1GB
instead of 3GB, according to Alexey's comment.

When I built the ksefltest on arm, I hit some 32bit related warnings.
Here are the patches to fix those issues.


 - [1/5] va_max was set 2^32 even on 32bit arch. This can make
        va_max == 0 and always fail. Make it 3GB on 32bit.
 - [2/5] Some VM tests requires 64bit user space, which should
        not run on 32bit arch.
 - [3/5] For counting the size of large file, we should use
        size_t instead of unsinged long.
 - [4/5] Gcc warns printf format for size_t and int64_t on
        32bit arch. Use %llu and cast it.
 - [5/5] Gcc warns __u64 and pointer type castings. It should
        once translated to unsigned long.

Thank you,

---
