* jfs: Set flags on quota files directlyJan Kara2017-04-191-2/+77
| | | | | | | | | Currently immutable and noatime flags on quota files are set by quota code which requires us to copy inode->i_flags to our on disk version of quota flags in GETFLAGS ioctl and copy_to_dinode(). Move to setting / clearing these on-disk flags directly to save that copying. Signed-off-by: Jan Kara <jack@suse.cz>

* reiserfs: Protect dquot_writeback_dquots() by s_umount semaphoreJan Kara2017-04-051-0/+14
| | | | | | | | | | | | | | | | | dquot_writeback_dquots() expects s_umount semaphore to be held to protect it from other concurrent quota operations. reiserfs_sync_fs() can call dquot_writeback_dquots() without holding s_umount semaphore when called from flush_old_commits(). Fix the problem by grabbing s_umount in flush_old_commits(). However we have to be careful and use only trylock since reiserfs_cancel_old_sync() can be waiting for flush_old_commits() to complete while holding s_umount semaphore. Possible postponing of sync work is not a big deal though as that is only an opportunistic flush.

* reiserfs: Make cancel_old_flush() reliableJan Kara2017-04-053-7/+17
| | | | | | | | | | | | | Currently canceling of delayed work that flushes old data using cancel_old_flush() does not prevent work from being requeued. Thus in theory new work can be queued after cancel_old_flush() from reiserfs_freeze() has run. This will become larger problem once flush_old_commits() can requeue the work itself. Fix the problem by recording in sbi->work_queue that flushing work is canceled and should not be requeued. Signed-off-by: Jan Kara <jack@suse.cz>
* ext2: Call dquot_writeback_dquots() with s_umount heldJan Kara2017-04-053-7/+7
| | | | | | | | | | | | | | | ext2_sync_fs() could be called without s_umount semaphore held when called through ext2_write_super() from __ext2_write_inode(). This function then calls dquot_writeback_dquots() which relies on s_umount to be held for protection against other quota operations. In fact __ext2_write_inode() does not need all the functionality ext2_write_super() provides. It is enough to just write the superblock. So use ext2_sync_super() instead.

After we have called both, all data is correct, but the first of the two reads uninitialized data for the type field and writes it back before it gets overwritten. This works around the warning by initializing the k_offset_v2 through the slightly larger memcpy().

* mm, swap: Remove WARN_ON_ONCE() in free_swap_slot()Huang Ying2017-03-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before commit 452b94b8c8c7 ("mm/swap: don't BUG_ON() due to uninitialized swap slot cache"), the following bug is reported, ------------[ cut here ]------------ kernel BUG at mm/swap_slots.c:270! invalid opcode: 0000 [#1] SMP CPU: 5 PID: 1745 Comm: (sd-pam) Not tainted 4.11.0-rc1-00243-g24c534bb161b #1 Hardware name: System manufacturer System Product Name/Z170-K, BIOS 1803 05/06/2016 RIP: 0010:free_swap_slot+0xba/0xd0 Call Trace: swap_free+0x36/0x40 do_swap_page+0x360/0x6d0 __handle_mm_fault+0x880/0x1080 handle_mm_fault+0xd0/0x240 __do_page_fault+0x232/0x4d0 do_page_fault+0x20/0x70 page_fault+0x22/0x30 ---[ end trace aefc9ede53e0ab21 ]--- This is raised by the BUG_ON(!swap_slot_cache_initialized) in free_swap_slot(). This is incorrect, because even if the swap slots cache fails to be initialized, the swap should operate properly without the swap slots cache. And the use_swap_slot_cache check later in the function will protect the uninitialized swap slots cache case. In commit 452b94b8c8c7, the BUG_ON() is replaced by WARN_ON_ONCE(). In the patch, the WARN_ON_ONCE() is removed too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reviewing the result of what was just added for Kconfig, we made a poor choice. It worked well for full kernel builds, but not so much for how it would be deployed on a distro. Here's the final result: - lpfc will compile in NVME initiator and/or NVME target support based on whether the kernel has the corresponding subsystem support. Kconfig is not used to drive this specifically for lpfc. - There is a module parameter, lpfc_enable_fc4_type, that indicates whether the ports will do FCP-only or FCP & NVME (NVME-only not yet possible due to dependency on fc transport). As FCP & NVME divvys up exchange resources, and given NVME will not be often initially, the default is changed to FCP only.

In this patch we combine advantage of both caches, so finally policy of the intermediate cache would be: - init: load free nid status from nat_bits into free_nid_bitmap - lookup: scan free_nid_bitmap before load NAT blocks - update: update free_nid_bitmap in real-time - persistence: udpate and persist nat_bits in checkpoint This patch also resolves performance regression reported by lkp-robot. commit: 4ac912427c4214d8031d9ad6fbc3bc75e71512df ("f2fs: introduce free nid bitmap") d00030cf9cd0bb96fdccc41e33d3c91dcbb672ba ("f2fs: use __set{__clear}_bit_le") 1382c0f3f9d3f936c8bc42ed1591cf7a593ef9f7 ("f2fs: combine nat_bits and free_nid_bitmap cache") 4ac912427c4214d8 d00030cf9cd0bb96fdccc41e33 1382c0f3f9d3f936c8bc42ed15 ---------------- -------------------------- -------------------------- %stddev %change %stddev %change %stddev \ | \ | \ 77863 ± 0% +2.1% 79485 ± 1% +50.8% 117404 ± 0% aim7.jobs-per-min 231.63 ± 0% -2.0% 227.01 ± 1% -33.6% 153.80 ± 0% aim7.time.elapsed_time 231.63 ± 0% -2.0% 227.01 ± 1% -33.6% 153.80 ± 0% aim7.time.elapsed_time.max 896604 ± 0% -0.8% 889221 ± 3% -20.2% 715260 ± 1% aim7.time.involuntary_context_switches 2394 ± 1% +4.6% 2503 ± 1% +3.7% 2481 ± 2% aim7.time.maximum_resident_set_size 6240 ± 0% -1.5% 6145 ± 1% -14.1% 5360 ± 1% aim7.time.system_time 1111357 ± 3% +1.9% 1132509 ± 2% -6.2% 1041932 ± 2% aim7.time.voluntary_context_switches ...

The code correctly checks whether the swap slot cache is usable or not, so an uninitialized swap slot cache is not actually problematic afaik. I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since I'm not sure why that seemingly pointless check was there. I suspect the real fix is to just remove it entirely, but for now we'll warn about it but not bring the machine down.

This is fine, but when the extension is not available we'll give a harmless, but scary warning. Instead check if the firmware supports HPT resizing before populating the mmu_hash_ops.resize_hpt pointer.
