Subject: compat: fix sys_fanotify_mark
From: Heiko Carstens <[email protected]>
commit 592f6b842f64e416c7598a1b97c649b34241e22d upstream.
Commit 91c2e0bcae72 ("unify compat fanotify_mark(2), switch to
COMPAT_SYSCALL_DEFINE") added a new unified compat fanotify_mark syscall
to be used by all architectures.
Unfortunately the unified version merges the split mask parameter in a
wrong way: the lower and higher word got swapped.
This was discovered with glibc's tst-fanotify test case.
