Subject: [PATCH 065/293] futex: recognise FUTEX_BITSET_MATCH_ANY bitmask
|
|
|
|
* xlat/futexbitset.in: New file.
|
|
* futex.c: Include "xlat/futexbitset.h".
|
|
(futex) <FUTEX_WAIT_BITSET, FUTEX_WAKE_BITSET>: Decode val3 using
|
|
futexbitset xlat.
|
|
* tests/futex.c: Add checks for 0xffffffff bitset mask printing.
|
|
|
|
Closes: Linux commit v4.16-rc1~166^2^2~2
