[Cluster-devel] [PATCH] gfs2: Disable page faults during lockless buffered reads

During lockless buffered reads, filemap_read() holds page cache page references while trying to copy data to the user-space buffer. The calling process isn't holding the inode glock, but the page references it holds prevent those pages from being removed from the page cache, and that prevents the

[Cluster-devel] [PATCH] gfs2: Fix should_fault_in_pages() logic

Fix the fault-in window size logic: * Use a maximum window size of 1 MiB instead of BIO_MAX_VECS * PAGE_SIZE. The previous window size was always one page because the pages variable was accidentally being redefined in should_fault_in_pages(). * Account for page overlap (unaligned iterators). *
