[Qemu-devel] [PULL 01/10] linux-user: fix O_TMPFILE handling

[riku . voipio]

From: Riku Voipio <address@hidden>

Since O_TMPFILE might differ between guest and host,
add it to the bitmask_transtbl. While at it, fix the definitions
of O_DIRECTORY etc which should arm32 according to kernel sources.

This fixes open14 and openat03 ltp testcases. Fixes:
