2020-09-25load_elf: Remove unused address variables from callersBALATON Zoltan
Several callers of load_elf() pass pointers for lowaddr and highaddr parameters which are then not used for anything. This may stem from a misunderstanding that load_elf need a value here but in fact it can take NULL to ignore these values. Remove such unused variables and pass NULL instead from callers that don't need these.

2020-09-25virtiofsd: Add -o allow_direct_io|no_allow_direct_io optionsJiachen Zhang
Due to the commit 65da4539803373ec4eec97ffc49ee90083e56efd, the O_DIRECT open flag of guest applications will be discarded by virtiofsd. While this behavior makes it consistent with the virtio-9p scheme when guest applications use direct I/O, we no longer have any chance to bypass the host page cache. Therefore, we add a flag 'allow_direct_io' to lo_data. If '-o no_allow_direct_io' option is added, or none of '-o allow_direct_io' or '-o no_allow_direct_io' is added, the 'allow_direct_io' will be set to 0, and virtiofsd discards O_DIRECT as before. If '-o allow_direct_io' is added to the starting command-line, 'allow_direct_io' will be set to 1, so that the O_DIRECT flags will be retained and host page cache can be bypassed.

2020-09-25virtiofsd: Used glib "shared" thread poolVivek Goyal
glib offers thread pools and it seems to support "exclusive" and "shared" thread pools. https://developer.gnome.org/glib/stable/glib-Thread-Pools.html#g-thread-pool-new Currently we use "exlusive" thread pools but its performance seems to be poor. I tried using "shared" thread pools and performance seems much better. I posted performance results here. https://www.redhat.com/archives/virtio-fs/2020-September/msg00080.html So lets switch to shared thread pools. We can think of making it optional once somebody can show in what cases exclusive thread pools offer better results. For now, my simple performance tests across the board see better results with shared thread pools.

2020-09-23qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi
clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

2020-09-23fdmon-poll: reset npfd when upgrading to fdmon-epollStefan Hajnoczi
npfd keeps track of how many pollfds are currently being monitored. It must be reset to 0 when fdmon_poll_wait() returns. When npfd reaches a treshold we switch to fdmon-epoll because it scales better. This patch resets npfd in the case where we switch to fdmon-epoll. Forgetting to do so results in the following assertion failure: util/fdmon-poll.c:65: fdmon_poll_wait: Assertion `npfd == 0' failed.
