Memory allocation problem in xfs

I recently saw case about memory allocation deadlock on below cite.

At this point solution seems cope with the high fragmentation. However, due to lack of knowledge for filesystem cache,
may I ask if using ext3 or ext4 can be another temporary solution where ? And if so why would it be the solution?

I am planning to build partitions on lvm with extent size of default 4MiB and block size default 4k.
