f2fs: check PageWriteback flag for ordered case

2018-12-26T23:16:56Z

For all ordered cases in f2fs_wait_on_page_writeback(), we need to check PageWriteback status, so let's clean up to relocate the check into f2fs_wait_on_page_writeback(). Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: add SPDX license identifiers

2018-09-12T20:07:10Z

Remove the verbose license text from f2fs files and replace them with SPDX tags. This does not change the license of any of the code. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: let checkpoint flush dnode page of regular

2018-08-01T18:52:36Z

Fsyncer will wait on all dnode pages of regular writeback before flushing, if there are async dnode pages blocked by IO scheduler, it may decrease fsync's performance. In this patch, we choose to let f2fs_balance_fs_bg() to trigger checkpoint to flush these dnode pages of regular, so async IO of dnode page can be elimitnated, making fsyncer only need to wait for sync IO.

f2fs: support in-memory inode checksum when checking consistency

2018-07-27T09:03:59Z

Enable in-memory inode checksum to protect metadata blocks from in-memory scribbles when checking consistency, which has no performance requirements. Signed-off-by: Weichao Guo Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: don't track new nat entry in nat set

2018-03-28T03:10:29Z

Nat entry set is used only in checkpoint(), and during checkpoint() we won't flush new nat entry with unallocated address, so we don't need to add new nat entry into nat set, then nat_entry_set::entry_cnt can indicate actual entry count we need to flush in checkpoint().

f2fs: remove unneeded set_cold_node()

2018-03-17T04:57:33Z

When setting COLD_BIT_SHIFT flag in node block, we only need to call set_cold_node() in new_node_page() and recover_inode_page() during node page initialization. So remove unneeded set_cold_node() in other places. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: allow to recover node blocks given updated checkpoint

2018-01-22T22:56:59Z

If fsck.f2fs changes crc, we have no way to recover some inode blocks by roll- forward recovery. Let's relax the condition to recover them. Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: limit # of inmemory pages

2017-10-26T08:44:21Z

If some abnormal users try lots of atomic write operations, f2fs is able to produce pinned pages in the main memory which affects system performance. This patch limits that as 20% over total memory size, and if f2fs reaches to the limit, it will drop all the inmemory pages. Signed-off-by: Jaegeuk Kim

f2fs: obsolete ALLOC_NID_LIST list

2017-10-10T19:49:53Z

As Fan Li reported, there is no user traversing nid_list[ALLOC_NID_LIST] which is used for tracking preallocated nids. Let's drop it, and only track preallocated nids in free_nid_root radix-tree. Reported-by: Fan Li Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: simplify the way of calulating next nat address

2017-07-04T09:11:34Z

The index of segment which the next nat block is in has only one different bit than the current one, so to get the next nat address, we can simply alter that one bit. Signed-off-by: Fan Li Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim
