ANDROID: sdcardfs: make it use new .rename i_op
Since commit 2773bf00aeb9 ("fs: rename "rename2" i_op to "rename""),
syscall rename2 is merged with rename syscall and it broke sdcard_fs
build and we get following build error:
CC [M] fs/sdcardfs/inode.o
fs/sdcardfs/inode.c:786:13: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
.rename = sdcardfs_rename,
^
fs/sdcardfs/inode.c:786:13: note: (near initialization for ‘sdcardfs_dir_iops.rename’)
renameat2 syscall is the same as renameat with an added flags argument
and calling renameat2 with flags=0 is equivalent to calling renameat.
