Subject: [PATCH] f2fs: fix to handle F2FS_IOC_START_ATOMIC_REPLACE in
 f2fs_compat_ioctl()
References: bsc#1012628
Patch-mainline: 6.2.5
Git-commit: 933141e4eb49d8b48721e2377835063a1e8fb823

[ Upstream commit 933141e4eb49d8b48721e2377835063a1e8fb823 ]

Otherwise, 32-bits binary call ioctl(F2FS_IOC_START_ATOMIC_REPLACE) will
fail in 64-bits kernel.
