* f2fs: avoid stale fi->gdirty_list pointerJaegeuk Kim2017-12-061-1/+3
| | | | | | | | When doing fault injection test, f2fs_evict_inode() didn't remove gdirty_list which incurs a kernel panic due to wrong pointer access. Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* f2fs: enhance multiple device flushChao Yu2017-12-061-0/+1
| | | | | | | | | | | | | When multiple device feature is enabled, during ->fsync we will issue flush in all devices to make sure node/data of the file being persisted into storage. But some flushes of device could be unneeded as file's data may be not writebacked into those devices. So this patch adds and manage bitmap per inode in global cache to indicate which device is dirty and it needs to issue flush during ->fsync, hence, we could improve performance of fsync in scenario of multiple device.

* f2fs: enhance on-disk inode structure scalabilityChao Yu2017-10-041-11/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add new flag F2FS_EXTRA_ATTR storing in inode.i_inline to indicate that on-disk structure of current inode is extended. In order to extend, we changed the inode structure a bit: Original one: struct f2fs_inode { ... struct f2fs_extent i_ext; __le32 i_addr[DEF_ADDRS_PER_INODE]; __le32 i_nid[DEF_NIDS_PER_INODE]; } Extended one: struct f2fs_inode { ... struct f2fs_extent i_ext; union { struct { __le16 i_extra_isize; __le16 i_padding; __le32 i_extra_end[0]; }; __le32 i_addr[DEF_ADDRS_PER_INODE]; }; __le32 i_nid[DEF_NIDS_PER_INODE]; } Once F2FS_EXTRA_ATTR is set, we will steal four bytes in the head of i_addr field for storing i_extra_isize and i_padding. with i_extra_isize, we can calculate actual size of reserved space in i_addr, available attribute fields included in total extra attribute fields for current inode can be described as below: +--------------------+ | .i_mode | | ... | | .i_ext | +--------------------+ | .i_extra_isize |-----+ | .i_padding | | | .i_prjid | | | .i_atime_extra | | | .i_ctime_extra | | | .i_mtime_extra |<----+ | .i_inode_cs |<----- store blkaddr/inline from here | .i_xattr_cs | | ... | +--------------------+ | | | block address | | | +--------------------+ | .i_nid | +--------------------+ | node_footer | | (nid, ino, offset) | +--------------------+ Hence, with this patch, we would enhance scalability of f2fs inode for storing more newly added attribute.

* f2fs: support plain user/group quotaChao Yu2017-07-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds to support plain user/group quota. Change Note by Jaegeuk Kim. - Use f2fs page cache for quota files in order to consider garbage collection. so, quota files are not tolerable for sudden power-cuts, so user needs to do quotacheck. - setattr() calls dquot_transfer which will transfer inode->i_blocks. We can't reclaim that during f2fs_evict_inode(). So, we need to count node blocks as well in order to match i_blocks with dquot's space. Note that, Chao wrote a patch to count inode->i_blocks without inode block. (f2fs: don't count inode block in in-memory inode.i_blocks) - in f2fs_remount, we need to make RW in prior to dquot_resume. - handle fault_injection case during f2fs_quota_off_umount - TODO: Project quota Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> Conflicts: fs/f2fs/namei.c fs/f2fs/super.c
* f2fs: don't count inode block in in-memory inode.i_blocksChao Yu2017-07-211-2/+2
| | | | | | | | | | | | | | | Previously, we count all inode consumed blocks including inode block, xattr block, index block, data block into i_blocks, for other generic filesystems, they won't count inode block into i_blocks, so for userspace applications or quota system, they may detect incorrect block count according to i_blocks value in inode. This patch changes to count all blocks into inode.i_blocks excluding inode block, for on-disk i_blocks, we keep counting inode block for backward compatibility.

* f2fs: measure inode.i_blocks as generic filesystemChao Yu2017-07-211-2/+3
| | | | | | | | | | | | | | | | Both in memory or on disk, generic filesystems record i_blocks with 512bytes sized sector count, also VFS sub module such as disk quota follows this rule, but f2fs records it with 4096bytes sized block count, this difference leads to that once we use dquota's function which inc/dec iblocks, it will make i_blocks of f2fs being inconsistent between in memory and on disk. In order to resolve this issue, this patch changes to make in-memory i_blocks of f2fs recording sector count instead of block count, meanwhile leaving on-disk i_blocks recording block count.
