befs_dump_super_block was called between befs_load_sb and befs_check_sb. It has been reported to crash (5/900) with null block testing. This patch loads, checks and only dump superblock if it's a valid one then brelse bh. (befs_dump_super_block uses disk_sb (bh->b_data) so it seems we need to call it before brelse(bh) but I don't know why befs_check_sb was called after brelse. Another thing I don't understand is why this problem appears now). Signed-off-by:

The original minix zmap blocks calculation was correct, in the formula of: sbi->s_nzones - sbi->s_firstdatazone + 1 It is sp->s_zones - (sp->s_firstdatazone - 1) in the minix3 source code. But a later commit 016e8d44 ("fs/minix: Verify bitmap block counts before mounting") has changed it unfortunately as: sbi->s_nzones - (sbi->s_firstdatazone + 1) This would show free blocks one block less than the real when the total data blocks are in "full zmap blocks plus one". This patch corrects that zmap blocks calculation and tidy a printk message while at it. Signed-off-by:

The interrupt handler gets the driver data associated with the RTC device and doesn't check it for validity. This can cause a NULL pointer being dereferenced when and interrupt fires before the driver data was properly set up. Fix this by setting the driver data earlier (before the interrupt is requested).

In particular seeing zero in eft->month is problematic, as it results in -1 (converted to unsigned int, i.e. yielding 0xffffffff) getting passed to rtc_year_days(), where the value gets used as an array index (normally resulting in a crash). This was observed with the driver enabled on x86 on some Fujitsu system (with possibly not up to date firmware, but anyway). Perhaps efi_read_alarm() should not fail if neither enabled nor pending are set, but the returned time is invalid? Signed-off-by:

Commit 5516f097 ("drivers/rtc/rtc-ds1742.c: remove redundant of_match_ptr() helper") has description as: "'ds1742_rtc_of_match' is always compiled in. Hence the helper macro is not needed". It is not true, of_match_ptr() macro makes of_device_id parameter unused and this constant is declared with __maybe_unused attribute, so normally this variable should be discarded by linker. This patch revers this commit, since there are no reason to compile of_device_id constant for non-DT systems. Signed-off-by:

Currently rootdelay=N and rootwait behave differently (aside from the obvious unbounded wait duration) because they are at different places in the init sequence. The difference manifests itself for md devices because the call to md_run_setup() lives between rootdelay and rootwait, so if you try to use rootdelay=20 to try and allow a slow RAID0 array to assemble, you get this: [ 4.526011] sd 6:0:0:0: [sdc] Attached SCSI removable disk [ 22.972079] md: Waiting for all devices to be available before autodetect i.e. you've achieved nothing other than delaying the probing 20s, when what you wanted was a 20s delay _after_ the probing for md devices was initiated. Here we move the rootdelay code to be right beside the rootwait code, so that their behaviour is consistent. It should be noted that in doing so, the actions based on the saved_root_name[0] and initrd_load() were previously put on hold by rootdelay=N and now currently will not be delayed. However, I think consistent behaviour is more important than matching historical behaviour of delaying the above two operations. Signed-off-by:

Charge migration currently disables IRQs twice to update the charge statistics for the old page and then again for the new page. But migration is a seamless transition of a charge from one physical page to another one of the same size, so this should be a non-event from an accounting point of view. Leave the statistics alone.

Pages are now uncharged at release time, and all sources of batched uncharges operate on lists of pages. Directly use those lists, and get rid of the per-task batching state. This also batches statistics accounting, in addition to the res counter charges, to reduce IRQ-disabling and re-enabling. Signed-off-by:

The memcg uncharging code that is involved towards the end of a page's lifetime - truncation, reclaim, swapout, migration - is impressively complicated and fragile. Because anonymous and file pages were always charged before they had their page->mapping established, uncharges had to happen when the page type could still be known from the context; as in unmap for anonymous, page cache removal for file and shmem pages, and swap cache truncation for swap pages. However, these operations happen well before the page is actually freed, and so a lot of synchronization is necessary: - Charging, uncharging, page migration, and charge migration all need to take a per-page bit spinlock as they could race with uncharging. - Swap cache truncation happens during both swap-in and swap-out, and possibly repeatedly before the page is actually freed. This means that the memcg swapout code is called from many contexts that make no sense and it has to figure out the direction from page state to make sure memory and memory+swap are always correctly charged. - On page migration, the old page might be unmapped but then reused, so memcg code has to prevent untimely uncharging in that case. Because this code - which should be a simple charge transfer - is so special-cased, it is not reusable for replace_page_cache(). But now that charged pages always have a page->mapping, introduce mem_cgroup_uncharge(), which is called after the final put_page(), when we know for sure that nobody is looking at the page anymore. For page migration, introduce mem_cgroup_migrate(), which is called after the migration is successful and the new page is fully rmapped. Because the old page is no longer uncharged after migration, prevent double charges by decoupling the page's memcg association (PCG_USED and pc->mem_cgroup) from the page holding an actual charge. The new bits PCG_MEM and PCG_MEMSW represent the respective charges and are transferred to the new page during migration. mem_cgroup_migrate() is suitable for replace_page_cache() as well, which gets rid of mem_cgroup_replace_page_cache(). However, care needs to be taken because both the source and the target page can already be charged and on the LRU when fuse is splicing: grab the page lock on the charge moving side to prevent changing pc->mem_cgroup of a page under migration. Also, the lruvecs of both pages change as we uncharge the old and charge the new during migration, and putback may race with us, so grab the lru lock and isolate the pages iff on LRU to prevent races and ensure the pages are on the right lruvec afterward. Swap accounting is massively simplified: because the page is no longer uncharged as early as swap cache deletion, a new mem_cgroup_swapout() can transfer the page's memory+swap charge (PCG_MEMSW) to the swap entry before the final put_page() in page reclaim. Finally, page_cgroup changes are now protected by whatever protection the page itself offers: anonymous pages are charged under the page table lock, whereas page cache insertions, swapin, and migration hold the page lock. Uncharging happens under full exclusion with no outstanding references. Charging and uncharging also ensure that the page is off-LRU, which serializes against charge migration. Remove the very costly page_cgroup lock and set pc->flags non-atomically.

These patches rework memcg charge lifetime to integrate more naturally with the lifetime of user pages. This drastically simplifies the code and reduces charging and uncharging overhead. The most expensive part of charging and uncharging is the page_cgroup bit spinlock, which is removed entirely after this series. Here are the top-10 profile entries of a stress test that reads a 128G sparse file on a freshly booted box, without even a dedicated cgroup (i.e. executing in the root memcg).

Worse, uncharge has to happen from a context that is still type-specific, rather than at the end of the page's lifetime with exclusive access, and so requires a lot of synchronization. Rewrite the charge API to provide a generic set of try_charge(), commit_charge() and cancel_charge() transaction operations, much like what's currently done for swap-in: mem_cgroup_try_charge() attempts to reserve a charge, reclaiming pages from the memcg if necessary. mem_cgroup_commit_charge() commits the page to the charge once it has a valid page->mapping and PageAnon() reliably tells the type. mem_cgroup_cancel_charge() aborts the transaction. This reduces the charge API and enables subsequent patches to drastically simplify uncharging. As pages need to be committed after rmap is established but before they are added to the LRU, page_add_new_anon_rmap() must stop doing LRU additions again. Revive lru_cache_add_active_or_unevictable().
