Hi,
Is it possible to do this scenario :
If one open a file first , he will get read/write permissions and other will get
read-only permission if they open the file after the first one.
CephFS will follow POSIX. If a client requests an exclusive write lock
than no one else will be able to get a write lock. This does not mean
that other clients will automatically receive a read-only lock, it
depends on the client if it will fall back to read-only or fail if it
can't get a write lock.
