Nomad creates tmpfs mounts with invalid options for the kernel version

Nomad version

1.9.5

Operating system and Environment details

Centos 8 (kernel 4.18)

Issue

For internal reasons we are required to use old kernels for some systems running legacy applications. This is one of those systems (using kernel 4.18). After deploying applications on the server we see spam in kernel messages like:

[12501231.085360] tmpfs: No value for mount option 'noswap'
[12501231.086722] tmpfs: No value for mount option 'noswap'
[12501231.092809] tmpfs: No value for mount option 'noswap'
[12501231.093503] tmpfs: No value for mount option 'noswap'

Reproduction steps

Use a system with kernel older than newer tmpfs implementation (pre 5.3 i think), which does not have noswap option.

Expected Result

No unnecessary kernel log spam

Actual Result

Unnecessary kernel log spam
