Acquiring 64 FMRs in rpcrdma_buffer_get() while holding the buffer pool lock is expensive, and unnecessary because FMR mode can transfer up to a 1MB payload using just a single ib_fmr. Instead, acquire ib_fmrs one-at-a-time as chunks are registered, and return them to rb_mws immediately during deregistration.
