[PATCH] xen: setup pv irq ops vector earlier

by Juergen Gross

Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage. Remove the no longer necessary conditional in xen_init_irq_ops() from PVH V1 times to make clear this is a PV only function.

[char-misc-next v2 1/2] mei: bus: type promotion bug in mei_nfc_if_version()

by Tomas Winkler

From: Dan Carpenter <dan.carpenter(a)oracle.com> We accidentally removed the check for negative returns without considering the issue of type promotion. The "if_version_length" variable is type size_t so if __mei_cl_recv() returns a negative then "bytes_recv" is type promoted to a high positive value and treated as success.

[PATCH V2] MIPS: implement smp_cond_load_acquire() for Loongson-3

by Huacai Chen

After commit 7f56b58a92aaf2c ("locking/mcs: Use smp_cond_load_acquire() in MCS spin loop") Loongson-3 fails to boot. This is because Loongson-3 has SFB (Store Fill Buffer) and the weak-ordering may cause READ_ONCE() to get an old value in a tight loop. So in smp_cond_load_acquire() we need a __smp_rmb() before the READ_ONCE() loop. This patch introduce a Loongson-specific smp_cond_load_acquire(). And it should be backported to as early as linux-4.5, in which release the smp_cond_acquire() is introduced. There may be other cases where memory barriers is needed, we will fix them one by one.

FAILED: patch "[PATCH] ovl: hash non-dir by lower inode for fsnotify" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 764baba80168ad3adafb521d2ab483ccbc49e344 Mon Sep 17 00:00:00 2001 From: Amir Goldstein <amir73il(a)gmail.com> Date: Sun, 4 Feb 2018 15:35:09 +0200 Subject: [PATCH] ovl: hash non-dir by lower inode for fsnotify Commit 31747eda41ef ("ovl: hash directory inodes for fsnotify") fixed an issue of inotify watch on directory that stops getting events after dropping dentry caches. A similar issue exists for non-dir non-upper files, for example: $ mkdir -p lower upper work merged $ touch lower/foo $ mount -t overlay -o lowerdir=lower,workdir=work,upperdir=upper none merged $ inotifywait merged/foo & $ echo 2 > /proc/sys/vm/drop_caches $ cat merged/foo inotifywait doesn't get the OPEN event, because ovl_lookup() called from 'cat' allocates a new overlay inode and does not reuse the watched inode. Fix this by hashing non-dir overlay inodes by lower real inode in the following cases that were not hashed before this change: - A non-upper overlay mount - A lower non-hardlink when index=off A helper ovl_hash_bylower() was added to put all the logic and documentation about which real inode an overlay inode is hashed by into one place. The issue dates back to initial version of overlayfs, but this patch depends on ovl_inode code that was introduced in kernel v4.13.
