* f2fs: give an option to enable in-place-updates during fsync to usersJaegeuk Kim2014-09-167-10/+33
| | | | | | | | | | | | | | | | | | | If user wrote F2FS_IPU_FSYNC:4 in /sys/fs/f2fs/ipu_policy, f2fs_sync_file only starts to try in-place-updates. And, if the number of dirty pages is over /sys/fs/f2fs/min_fsync_blocks, it keeps out-of-order manner. Otherwise, it triggers in-place-updates. This may be used by storage showing very high random write performance. For example, it can be used when, Seq. writes (Data) + wait + Seq. writes (Node) is pretty much slower than, Rand. writes (Data) Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* f2fs: fix negative value for lseek offsetJaegeuk Kim2014-09-091-0/+2
| | | | | | | | | | | | | | | If application throws negative value of lseek with SEEK_DATA|SEEK_HOLE, previous f2fs went into BUG_ON in get_dnode_of_data, which was reported by Tommi Rantala. He could make a simple code to detect this having: lseek(fd, -17595150933902LL, SEEK_DATA); This patch should resolve that bug.

* f2fs: avoid node page to be written twice in gc_node_segmentHuang Ying2014-09-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gc_node_segment, if node page gc is run concurrently with node page writeback, and check_valid_map and get_node_page run after page locked and before cur_valid_map is updated as below, it is possible for the page to be written twice unnecessarily. sync_node_pages try_lock_page ... check_valid_map f2fs_write_node_page ... write_node_page do_write_page allocate_data_block ... refresh_sit_entry /* update cur_valid_map */ ... ... unlock_page get_node_page ... set_page_dirty ... f2fs_put_page unlock_page This can be solved via calling check_valid_map after get_node_page again.

* f2fs: use lock-less list(llist) to simplify the flush cmd managementGu Zheng2014-09-092-25/+12
| | | | | | | | | | | | | | | | | | We use flush cmd control to collect many flush cmds, and flush them together. In this case, we use two list to manage the flush cmds (collect and dispatch), and one spin lock is used to protect this. In fact, the lock-less list(llist) is very suitable to this case, and we use simplify this routine. - v2: -use llist_for_each_entry_safe to fix possible use-after-free issue. -remove the unused field from struct flush_cmd.

* f2fs: refactor flush_sit_entries codes for reducing SIT writesChao Yu2014-09-094-71/+186
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit aec71382c681 ("f2fs: refactor flush_nat_entries codes for reducing NAT writes"), we descripte the issue as below: "Although building NAT journal in cursum reduce the read/write work for NAT block, but previous design leave us lower performance when write checkpoint frequently for these cases: 1. if journal in cursum has already full, it's a bit of waste that we flush all nat entries to page for persistence, but not to cache any entries. 2. if journal in cursum is not full, we fill nat entries to journal util journal is full, then flush the left dirty entries to disk without merge journaled entries, so these journaled entries may be flushed to disk at next checkpoint but lost chance to flushed last time." Actually, we have the same problem in using SIT journal area. In this patch, firstly we will update sit journal with dirty entries as many as possible. Secondly if there is no space in sit journal, we will remove all entries in journal and walk through the whole dirty entry bitmap of sit, accounting dirty sit entries located in same SIT block to sit entry set. All entry sets are linked to list sit_entry_set in sm_info, sorted ascending order by count of entries in set. Later we flush entries in set which have fewest entries into journal as many as we can, and then flush dense set with merged entries to disk. In this way we can use sit journal area more effectively, also we will reduce SIT update, result in gaining in performance and saving lifetime of flash device. In my testing environment, it shows this patch can help to reduce SIT block update obviously. virtual machine + hard disk: fsstress -p 20 -n 400 -l 5 sit page num cp count sit pages/cp based 2006.50 1349.75 1.486 patched 1566.25 1463.25 1.070 Our latency of merging op is small when handling a great number of dirty SIT entries in flush_sit_entries: latency(ns) dirty sit count 36038 2151 49168 2123 37174 2232 Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | Theoretically, our total inodes number is the same as total node number, but there are three node ids are reserved in f2fs, they are 0, 1 (node nid), and 2 (meta nid), and they should never be used by user, so our total/free inode number calculated in ->statfs is wrong.

Then, writing checkpoint/dentry/node blocks is not allowed. Note that, for the data pages, we can't just throw away by redirtying them. Otherwise, kworker can fall into infinite loop to flush them.

That indicates an object of size 0x956 - a four byte discrepency, presumably just padding for alignment purposes.

Whilst we're at it, allow shorter PKCS#7 objects that manage to squeeze within 127 or 255 bytes. It's just about conceivable if no X.509 certs are included in the PKCS#7 message.

They address some issues found by running smatch on the arch code (ignoring the false positives) and also stop 32-bit Android from losing track of its stack. There's one additional irq migration fix in the pipeline, but it came in after I'd tagged and tested this set. - a few fixes for real issues found by smatch (after Dan's talk at KS) - revert the /proc/cpuinfo changes merged during the merge window. We've opened a can of worms here, so we need to find out where we stand before we change this interface. - implement KSTK_ESP for compat tasks, otherwise 32-bit Android gets confused wondering where its [stack] has gone - misc fixes (fpsimd context handling, crypto, ...)" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: Revert "arm64: cpuinfo: print info for all CPUs" arm64: fix bug for reloading FPSIMD state after cpu power off arm64: report correct stack pointer in KSTK_ESP for compat tasks arm64: Add brackets around user_stack_pointer() arm64: perf: don't rely on layout of pt_regs when grabbing sp or pc arm64: ptrace: fix compat reg getter/setter return values arm64: ptrace: fix compat hardware watchpoint reporting arm64: Remove unused variable in head.S arm64/crypto: remove redundant update of data
