[Gluster-devel] WORM-Xlator: How to get filepath in worm_create_cbk?

Hello Amar,
I do the following in worm_create_cbk:

char *filepath = NULL;
inode_path(inode, NULL, &filepath);
if (!filepath) {
    gf_log(this->name, GF_LOG_ERROR, "Can't get filepath!");

Unfortunately I got this in the brick log:
[2020-02-05 10:09:41.880522] E [inode.c:1498:__inode_path]
[0x7f4657df7129] -->/usr/lib64/libglusterfs.so.0(inode_path+0x31)

0-repo2-worm: invalid inode [Invalid argument]
[2020-02-05 10:09:41.880594] E [worm.c:488:worm_create_cbk] 0-repo2-worm:
Can't get filepath!

The inode I use seems to be not valid because inode_path() returns with
error. The same with fd->inode. Is there a way to validate the inode before
passing it to the function?
