2016-09-30f2fs: fix to commit bio cache after flushing node pagesChao Yu1-2/+16
In sync_node_pages, we won't check and commit last merged pages in private bio cache of f2fs, as these pages were taged as writeback, someone who is waiting for writebacking of the page will be blocked until the cache was committed by someone else. We need to commit node type bio cache to avoid potential deadlock or long delay of waiting writeback. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2016-09-30f2fs: support configuring fault injection per superblockChao Yu10-94/+65
Previously, we only support global fault injection configuration, so that when we configure type/rate of fault injection through sysfs, mount option, it will influence all f2fs partition which is being used. It is not make sence, since it will be not convenient if developer want to test separated partitions with different fault injection rate/type simultaneously, also it's not possible to enable fault injection in one partition and disable fault injection in other one. >From now on, we move global configuration of fault injection in module into per-superblock, hence injection testing can be more flexible.

Instead of the fallback releasing page path, it provides better performance for memory compaction, CMA and other users of memory page migrating. For dirty pages, there is no need to write back first when migrating. For an atomic written page before committing, we can migrate the page and update the related 'inmem_pages' list at the same time.

2016-09-30f2fs: use crc and cp version to determine roll-forward recoveryJaegeuk Kim6-100/+62
Previously, we used cp_version only to detect recoverable dnodes. In order to avoid same garbage cp_version, we needed to truncate the next dnode during checkpoint, resulting in additional discard or data write. If we can distinguish this by using crc in addition to cp_version, we can remove this overhead. There is backward compatibility concern where it changes node_footer layout. So, this patch introduces a new checkpoint flag, CP_CRC_RECOVERY_FLAG, to detect new layout. New layout will be activated only when this flag is set. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2016-09-13f2fs: fix to set PageUptodate in f2fs_write_end correctlyJaegeuk Kim1-10/+19
Previously, f2fs_write_begin sets PageUptodate all the time. But, when user tries to update the entire page (i.e., len == PAGE_SIZE), we need to consider that the page is able to be copied partially afterwards. In such the case, we will lose the remaing region in the page. This patch fixes this by setting PageUptodate in f2fs_write_end as given copied result. In the short copy case, it returns zero to let generic_perform_write retry copying user data again. As a result, f2fs_write_end() works: PageUptodate len copied return retry 1. no 4096 4096 4096 false -> return 4096 2. no 4096 1024 0 true -> goto #1 case 3. yes 2048 2048 2048 false -> return 2048 4. yes 2048 1024 1024 false -> return 1024 Suggested-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2016-09-07f2fs: support async discardChao Yu4-2/+99
Like most filesystems, f2fs will issue discard command synchronously, so when user trigger fstrim through ioctl, multiple discard commands will be issued serially with sync mode, which makes poor performance. In this patch we try to support async discard, so that all discard commands can be issued and be waited for endio in batch to improve performance.

2016-09-07f2fs: fix to do security initialization of encrypted inode with original ↵Chao Yu3-20/+26
filename When creating new inode, security_inode_init_security will be called for initializing security info related to the inode, and filename is passed to security module, it helps security module such as SElinux to know which rule or label could be applied for the inode with specified name. Previously, if new inode is created as an encrypted one, f2fs will transfer encrypted filename to security module which may fail the check of security policy belong to the inode. So in order to this issue, alter to transfer original unencrypted filename instead. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2016-09-07f2fs: do in batch synchronously readahead during GCChao Yu1-10/+23

2016-09-07f2fs: schedule in between two continous batch discardsChao Yu1-0/+2
In batch discard approach of fstrim will grab/release gc_mutex lock repeatly, it makes contention of the lock becoming more intensive. So after one batch discards were issued in checkpoint and the lock was released, it's better to do schedule() to increase opportunity of grabbing gc_mutex lock for other competitors.
