[yocto] [Yocto-bsp] Error of " fs.inotify.max_user_watches " while using bitbake [ Yocto-2.6.1 + Qemux86]

[AshishKumar Mishra]

Yes , i checked the value & increased it 64K ( got pointer from
https://hub.docker.com/r/wolverine2k/yocto-build-env/)

It got the same error again today .
Currently i have increased the value from 64K to 512K.
But raised the query to check if i am doing any thing wrong here or missing
any caution.

Like if at 512K if we get the error again , not sure if increasing the
value is the only value.

Thanks
Ashish
