[f2fs-dev] [PATCH 1/2] f2fs: introduce F2FS_INODE macro to get f2fs_inode

This patch introduces F2FS_INODE that returns struct f2fs_inode * from the inode page. By using this macro, we can remove unnecessary casting codes like below. struct f2fs_inode *ri = &F2FS_NODE(inode_page)->i; -> struct f2fs_inode *ri = F2FS_INODE(inode_page); Signed-off-by: Jaegeuk Kim ---

[f2fs-dev] [PATCH 2/2] f2fs: should put the dnode when NEW_ADDR is detected

When get_dnode_of_data() in get_data_block() returns a successful dnode, we should put the dnode. But, previously, if its data block address is equal to NEW_ADDR, we didn't do that, resulting in a deadlock condition. So, this patch splits original error conditions with this case, and then calls f2f

[f2fs-dev] [PATCH] f2fs: convert max_orphans to a field of f2fs_sb_info

Previously, we need to calculate the max orphan num when we try to acquire an orphan inode, but it's a stable value since the super block was inited. So converting it to a field of f2fs_sb_info and use it directly when needed seems a better choose. Signed-off-by: Gu Zheng --- fs/f2fs/checkpoint.

[f2fs-dev] [PATCH] f2fs: check the blocksize before calling generic_direct_IO path

The f2fs supports 4KB block size. If user requests dwrite with under 4KB data, it allocates a new 4KB data block. However, f2fs doesn't add zero data into the untouched data area inside the newly allocated data block. This incurs an error during the xfstest #263 test as follow. 263 12s ... [faile

[f2fs-dev] [PATCH 4/6] f2fs: refactor f2fs_convert_inline_data

This patch refactors f2fs_convert_inline_data to check a couple of conditions internally for deciding whether it needs to convert inline_data or not. So, the new f2fs_convert_inline_data initially checks: 1) f2fs_has_inline_data(), and 2) the data size to be changed. If the inode has inline_data

[f2fs-dev] [PATCH 1/6] f2fs: don't need to get f2fs_lock_op for the inline_data test
