Hi
During copying a large file (about 200GB) to a backup hard drive, I am 
getting a multitude of XFS possible memory allocation deadlock messages.
RedHat Portal shows the following:

XFS issues "possible memory allocation deadlock in kmem_alloc" messages
Solution Verified - Updated August 9 2019 at 2:51 AM - English
Issue

     Seeing file system access issues on XFS based file systems.
     dmesg shows continuous entries with:

     XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250)

Does anyone know what the solution is? And if SL7 will get this solution 
soon?

Cheers
Bill
