is TMPFS still highly experimental?

[Robert Millan]

Hi,

Is TMPFS still considered highly experimental? I notice a warning
saying this was added in 2007:

fs/tmpfs/tmpfs_vfsops.c:        printf("WARNING: TMPFS is considered
to be a highly experimental "

Since it's very old, I wonder if it still applies. After 4 years and
54 commits, can someone tell if the maturity of this file system has
improved significantly?
