This patch avoids fuse hangs on sh4 by flushing the cache on get_user_pages_fast(). This is not necessary a good thing to do, but get_user_pages() does this, so get_user_pages_fast() should too. Please note the patch for mips arch that addresses the similar problem: https://kernel.googlesource.com/pub/scm/linux/kernel/git/ralf/linux/+/linux-3.4.50%5E!/#F0 They basically simply disable get_user_pages_fast() at all, using a fall-back to get_user_pages(). But my fix is different, it adds an explicit cache flushes.
