f2fs: remove unneeded INIT_LIST_HEAD at few places

2013-01-04T00:42:59Z

While creating a new entry for addition to the list(orphan inode list and fsync inode entry list), there is no need to call HEAD initialization for these entries. So, remove that init part. Signed-off-by: Namjae Jeon Signed-off-by: Amit Sahrawat Signed-off-by: Jaegeuk Kim

f2fs: fix endian conversion bugs reported by sparse

2012-12-11T04:43:42Z

This patch should resolve the bugs reported by the sparse tool. Initial reports were written by "kbuild test robot" managed by fengguang.wu. In my local machines, I've tested also by running: > make C=2 CF="-D__CHECK_ENDIAN__" Accordingly, I've found lots of warnings and bugs related to the endian conversion. And I've fixed all at this moment. Signed-off-by: Jaegeuk Kim

f2fs: add checkpoint operations

2012-12-11T04:43:40Z

This adds functions required by the checkpoint operations. Basically, f2fs adopts a roll-back model with checkpoint blocks written in the CP area. The checkpoint procedure includes as follows. - write_checkpoint() 1. block_operations() freezes VFS calls. 2. submit cached bios. 3. flush_nat_entries() writes NAT pages updated by dirty NAT entries. 4. flush_sit_entries() writes SIT pages updated by dirty SIT entries. 5. do_checkpoint() writes, - checkpoint block (#0) - orphan inode blocks - summary blocks made by active logs - checkpoint block (copy of #0) 6. unblock_opeations() In order to provide an address space for meta pages, f2fs_sb_info has a special inode, namely meta_inode. This patch also adds the address space operations for meta_inode. Signed-off-by: Chul Lee Signed-off-by: Jaegeuk Kim
