Normally, we use title like "sload.f2fs: xxx" to indicate this is a patch of
f2fs-tools, otherwise it looks like a kernel one.
It's local filesystem change, so

Add a flag option to get xattr method that could have a bit flag of

Because of the overlayfs getxattr recursion, the incoming inode fails
to update the selinux sid resulting in avc denials being reported

Solution is to respond to the XATTR_NOSECURITY flag in get xattr
method that calls the __vfs_getxattr handler

When the -m option is specified to format a Zoned device,
do not fall back to the non-zoned mode in case information
about the device is not found.
Explicitly specify this error to the user.

Hi Surbhi,
This patch looks good to me, unless we'd better change patch title a little as
"libf2fs: throw an " to indicate which part of f2fs we patched.
Anyway, please add below tag in your next version:
