It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could be zero.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net coming late in the 5.17-rc process: 1) Revert port remap to mitigate shadowing service ports, this is causing problems in existing setups and this mitigation can be achieved with explicit ruleset, eg. ... tcp sport < 16386 tcp dport >= 32768 masquerade random This patches provided a built-in policy similar to the one described above. 2) Disable register tracking infrastructure in nf_tables. Florian reported two issues: - Existing expressions with no implemented .reduce interface that causes data-store on register should cancel the tracking. - Register clobbering might be possible storing data on registers that are larger than 32-bits. This might lead to generating incorrect ruleset bytecode. These two issues are scheduled to be addressed in the next release cycle. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: disable register tracking Revert "netfilter: conntrack: tag conntracks picked up in local out hook" Revert "netfilter: nat: force port remap to prevent shadowing well-known ports" ==================== Link: https://lore.kernel.org/r/20220312220315.64531-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Let's start supporting static DRRS by trying to match the refresh rate the user has requested, assuming the panel supports suitable timings. For now we stick to just our current two timings: - fixed_mode: the panel's preferred mode - downclock_mode: the lowest refresh rate mode we found Some panels may support more timings than that, but we'll have to convert our fixed_mode/downclock_mode pointers into a full list before we can handle that. v2: Rebase due to intel_panel_get_modes() Reviewed-by: Jani Nikula <jani.nikula@intel.com> #v1 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220311172428.14685-16-ville.syrjala@linux.intel.com

2022-03-14block: fix rq-qos breakage from skipping rq_qos_done_bio()Tejun Heo4-13/+15
a647a524a467 ("block: don't call rq_qos_ops->done_bio if the bio isn't tracked") made bio_endio() skip rq_qos_done_bio() if BIO_TRACKED is not set. While this fixed a potential oops, it also broke blk-iocost by skipping the done_bio callback for merged bios. Before, whether a bio goes through rq_qos_throttle() or rq_qos_merge(), rq_qos_done_bio() would be called on the bio on completion with BIO_TRACKED distinguishing the former from the latter. rq_qos_done_bio() is not called for bios which wenth through rq_qos_merge(). This royally confuses blk-iocost as the merged bios never finish and are considered perpetually in-flight. One reliably reproducible failure mode is an intermediate cgroup geting stuck active preventing its children from being activated due to the leaf-only rule, leading to loss of control. The following is from resctl-bench protection scenario which emulates isolating a web server like workload from a memory bomb run on an iocost configuration which should yield a reasonable level of protection. # cat /sys/block/nvme2n1/device/model Samsung SSD 970 PRO 512GB # cat /sys/fs/cgroup/io.cost.model 259:0 ctrl=user model=linear rbps=834913556 rseqiops=93622 rrandiops=102913 wbps=618985353 wseqiops=72325 wrandiops=71025 # cat /sys/fs/cgroup/io.cost.qos 259:0 enable=1 ctrl=user rpct=95.00 rlat=18776 wpct=95.00 wlat=8897 min=60.00 max=100.00 # resctl-bench -m 29.6G -r out.json run protection::scenario=mem-hog,loops=1 ...

Fix it by introducing a new flag BIO_QOS_MERGED to mark merged bios and calling rq_qos_done_bio() on them too. For consistency and clarity, rename BIO_TRACKED to BIO_QOS_THROTTLED. The flag checks are moved into rq_qos_done_bio() so that it's next to the code paths that set the flags.

2022-03-14block: release rq qos structures for queue without diskMing Lei1-0/+4
blkcg_init_queue() may add rq qos structures to request queue, previously blk_cleanup_queue() calls rq_qos_exit() to release them, but commit 8e141f9eb803 ("block: drain file system I/O on del_gendisk") moves rq_qos_exit() into del_gendisk(), so memory leak is caused because queues may not have disk, such as un-present scsi luns, nvme admin queue, ... Fixes the issue by adding rq_qos_exit() to blk_cleanup_queue() back. BTW, v5.18 won't need this patch any more since we move blkcg_init_queue()/blkcg_exit_queue() into disk allocation/release handler, and patches have been in for-5.18/block.

2022-03-14fs: Convert is_partially_uptodate to foliosMatthew Wilcox (Oracle)8-48/+40
Since the uptodate property is maintained on a per-folio basis, the is_partially_uptodate method should also take a folio. Fix the types at the same time so it's clear that it returns true/false and takes the count in bytes, not blocks.

While there is no intent to use large folios in filesystems using buffer heads, converting the filesystems to use single-page folios is still worth doing to remove legacy infrastructure and hidden calls to compound_head(). These helper functions are needed for that conversion to take place.

While read_cache_page() takes a void *, because you can pass a pointer to anything as the first argument of filler_t, if we are calling read_mapping_page(), it will be passed as the first argument of ->readpage, so we know this must be a struct file pointer, and we should let the compiler enforce that for us.
