Jaegeuk Kim 6522a6d452 f2fs: updates on 4.15-rc1 ... Pull f2fs updates from Jaegeuk Kim: "In this round, we introduce sysfile-based quota support which is required for Android by default. In addition, we allow that users are able to reserve some blocks in runtime to mitigate performance drops in low free space. Enhancements: - assign proper data segments according to write_hints given by user - issue cache_flush on dirty devices only among multiple devices - exploit cp_error flag and add more faults to enhance fault injection test - conduct more readaheads during f2fs_readdir - add a range for discard commands Bug fixes: - fix zero stat->st_blocks when inline_data is set - drop crypto key and free stale memory pointer while evict_inode is failing - fix some corner cases in free space and segment management - fix wrong last_disk_size This series includes lots of clean-ups and code enhancement in terms of xattr operations, discard/flush command control. In addition, it adds versatile debugfs entries to monitor f2fs status" Cherry-picked from origin/upstream-f2fs-stable-linux-4.4.y: 56a07b0705 f2fs: deny accessing encryption policy if encryption is off c394842e26 f2fs: inject fault in inc_valid_node_count 9262922510 f2fs: fix to clear FI_NO_PREALLOC e6cfc5de2d f2fs: expose quota information in debugfs c4cd2efe83 f2fs: separate nat entry mem alloc from nat_tree_lock 48c72b4c8c f2fs: validate before set/clear free nat bitmap baf9275a4b f2fs: avoid opened loop codes in __add_ino_entry 47af6c72d9 f2fs: apply write hints to select the type of segments for buffered write ac98191605 f2fs: introduce scan_curseg_cache for cleanup ca28e9670e f2fs: optimize the way of traversing free_nid_bitmap 460688b59e f2fs: keep scanning until enough free nids are acquired 0186182c0c f2fs: trace checkpoint reason in fsync() 5d4b6efcfd f2fs: keep isize once block is reserved cross EOF 3c8f767e13 f2fs: avoid race in between GC and block exchange 4423778adf f2fs: save a multiplication for last_nid calculation 3e3b405575 f2fs: fix summary info corruption 44889e4879 f2fs: remove dead code in update_meta_page 55c7b9595b f2fs: remove unneeded semicolon 8b92814117 f2fs: don't bother with inode->i_version 42c7c71824 f2fs: check curseg space before foreground GC c5470498e5 f2fs: use rw_semaphore to protect SIT cache 82750d346a f2fs: support quota sys files 26dfec49b2 f2fs: add quota_ino feature infra ddb8e2ae98 f2fs: optimize __update_nat_bits f46ae958c7 f2fs: modify for accurate fggc node io stat c713fdb5a2 Revert "f2fs: handle dirty segments inside refresh_sit_entry" 873ec505cb f2fs: add a function to move nid ae66786296 f2fs: export SSR allocation threshold 90c28a18d2 f2fs: give correct trimmed blocks in fstrim 5612922fb0 f2fs: support bio allocation error injection 583b7a274c f2fs: support get_page error injection 09a073cc8c f2fs: add missing sysfs description e945474a9c f2fs: support soft block reservation b7b2e629b6 f2fs: handle error case when adding xattr entry 7368e30495 f2fs: support flexible inline xattr size ada4061e19 f2fs: show current cp state 5b8ff1301a f2fs: add missing quota_initialize 46d4a691f0 f2fs: show # of dirty segments via sysfs fc13f9d7ce f2fs: stop all the operations by cp_error flag 91bea0c391 f2fs: remove several redundant assignments 807486c795 f2fs: avoid using timespec 03b1cb0bb4 f2fs: fix to correct no_fggc_candidate 5c15033cea Revert "f2fs: return wrong error number on f2fs_quota_write" 5f5f593222 f2fs: remove obsolete pointer for truncate_xattr_node 032a690682 f2fs: retry ENOMEM for quota_read|write 171b638fc4 f2fs: limit # of inmemory pages 83ed7a615f f2fs: update ctx->pos correctly when hitting hole in directory 4d6e68be25 f2fs: relocate readahead codes in readdir() c8be47b540 f2fs: allow readdir() to be interrupted 2b903fe94c f2fs: trace f2fs_readdir bb0db666d4 f2fs: trace f2fs_lookup 40d6250f04 f2fs: skip searching non-exist range in truncate_hole 8e84f379df f2fs: expose some sectors to user in inline data or dentry case cb98f70dea f2fs: avoid stale fi->gdirty_list pointer 5562a3c539 f2fs/crypto: drop crypto key at evict_inode only 85853e7e38 f2fs: fix to avoid race when accessing last_disk_size 0c47a892d5 f2fs: Fix bool initialization/comparison 68e801abc5 f2fs: give up CP_TRIMMED_FLAG if it drops discards df74eacb20 f2fs: trace f2fs_remove_discard bd502c6e3e f2fs: reduce cmd_lock coverage in __issue_discard_cmd a34ab5ca4f f2fs: split discard policy 1e65afd14d f2fs: wrap discard policy 684447dad1 f2fs: support issuing/waiting discard in range 27eaad0938 f2fs: fix to flush multiple device in checkpoint 08bb9d68d5 f2fs: enhance multiple device flush 9c2526ac2e f2fs: fix to show ino management cache size correctly 814b463d26 f2fs: drop FI_UPDATE_WRITE tag after f2fs_issue_flush f555b0a117 f2fs: obsolete ALLOC_NID_LIST list 75d3164ae1 f2fs: convert inline data for direct I/O & FI_NO_PREALLOC 4de0ceb6b7 f2fs: allow readpages with NULL file pointer 322a45d172 f2fs: show flush list status in sysfs 6d625a93b4 f2fs: introduce read_xattr_block 8ea6e1c327 f2fs: introduce read_inline_xattr dbce11e9ee Revert "f2fs: reuse nids more aggressively" 131bc9f6b7 Revert "f2fs: node segment is prior to data segment selected victim" Change-Id: I93b9cd867b859a667a448b39299ff44a2b841b8c Signed-off-by: Jaegeuk Kim <jaegeuk@google.com>		2018-01-22 13:15:43 +05:30
