[PATCH v2] eventpoll: fix missing wakeup for ovflist in ep_poll_callback

by Khazhismel Kumykov

In the event that we add to ovflist, before 339ddb53d373 we would be woken up by ep_scan_ready_list, and did no wakeup in ep_poll_callback. With that wakeup removed, if we add to ovflist here, we may never wake up. Rather than adding back the ep_scan_ready_list wakeup - which was resulting in unnecessary wakeups, trigger a wake-up in ep_poll_callback. We noticed that one of our workloads was missing wakeups starting with 339ddb53d373 and upon manual inspection, this wakeup seemed missing to me. With this patch added, we no longer see missing wakeups. I haven't yet tried to make a small reproducer, but the existing kselftests in filesystem/epoll passed for me with this patch.

[PATCH] gfs2: More gfs2_find_jhead fixes

by Andreas Gruenbacher

It turns out that when extending an existing bio, gfs2_find_jhead fails to check if the block number is consecutive, which leads to incorrect reads for fragmented journals. In addition, limit the maximum bio size to an arbitrary value of 2 megabytes: since commit 07173c3ec276 ("block: enable multipage bvecs"), if we just keep adding pages until bio_add_page fails, bios will grow much larger than useful, which pins more memory than necessary with barely any additional performance gains.

[PATCH] gfs2: Another gfs2_walk_metadata fix

by Andreas Gruenbacher

Make sure we don't walk past the end of the metadata in gfs2_walk_metadata: the inode holds fewer pointers than indirect blocks. Slightly clean up gfs2_iomap_get.

[PATCH 1/3] powerpc/xive: Clear the page tables for the ESB IO mapping

by Cédric Le Goater

Commit 1ca3dec2b2df ("powerpc/xive: Prevent page fault issues in the machine crash handler") fixed an issue in the FW assisted dump of machines using hash MMU and the XIVE interrupt mode under the POWER hypervisor. It forced the mapping of the ESB page of interrupts being mapped in the Linux IRQ number space to make sure the 'crash kexec' sequence worked during such an event. But it didn't handle the un-mapping. This mapping is now blocking the removal of a passthrough IO adapter under the POWER hypervisor because it expects the guest OS to have cleared all page table entries related to the adapter. If some are still present, the RTAS call which isolates the PCI slot returns error 9001 "valid outstanding translations". Remove these mapping in the IRQ data cleanup routine. Under KVM, this cleanup is not required because the ESB pages for the adapter interrupts are un-mapped from the guest by the hypervisor in the KVM XIVE native device. This is now redundant but it's harmless.
