In f2fs_inode_info structure, the description for data_version has a typo mistake. It should be latest instead of lastes. So, correcting that.

This patch enhances the checkpoint routine to cope with IO errors. Basically f2fs detects IO errors from end_io_write, and the errors are able to be occurred during one of data, node, and meta page writes. In the previous code, when an IO error is occurred during writes, f2fs sets a flag, CP_ERROR_FLAG, in the raw ckeckpoint buffer which will be written to disk. Afterwards, write_checkpoint() will check the flag and remount f2fs as a read-only (ro) mode. However, even once f2fs is remounted as a ro mode, dirty checkpoint pages are freely able to be written to disk by flusher or kswapd in background. In such a case, after cold reboot, f2fs would restore the checkpoint data having CP_ERROR_FLAG, resulting in disabling write_checkpoint and remounting f2fs as a ro mode again. Therefore, let's prevent any checkpoint page (meta) writes once an IO error is occurred, and remount f2fs as a ro mode right away at that moment.

As the "status" debugfs entry will be maintained for entire F2FS filesystem irrespective of the number of partitions. So, we can move the initialization to the init part of the f2fs and destroy will be done from exit part. After making changes, for individual partition mount - entry creation code will not be executed.

I'd like to revisit the f2fs_gc flow and rewrite as follows. 1. In practical, the nGC parameter of f2fs_gc is meaningless. So, let's remove it. 2. Background GC marks victim blocks as dirty one at a time. 3. Foreground GC should do cleaning job until acquiring enough free sections. Afterwards, it needs to do checkpoint.

This patch resolves Coverity #753112. In practical, the existing code flow does not fall into the reported errorneous path. But, anyway, let's avoid this for future. Signed-off-by: NJaegeuk Kim <jaegeuk.kim@samsung.com>

Introduced f2fs_msg function to differentiate f2fs specific messages in the log. And, added few informative prints in the mount path, to convey proper error in case of mount failure.

This patch is intended to unify string length declarations and usage. There are number of calls to strlen which return size_t object. The size of this object depends on compiler if it will be bigger, equal or even smaller than an unsigned int Signed-off-by: NLeon Romanovsky <leon@leon.nu> Signed-off-by: NJaegeuk Kim <jaegeuk.kim@samsung.com>

Previously, f2fs didn't track the parent inode number correctly which is stored in each f2fs_inode. In the case of the following scenario, a bug can be occured. Let's suppose there are one directory, "/b", and two files, "/a" and "/b/a". - pino of "/a" is ROOT_INO. - pino of "/b/a" is DIR_B_INO. Then, # sync : The inode pages of "/a" and "/b/a" contain the parent inode numbers as ROOT_INO and DIR_B_INO respectively. # mv /a /b/a : The parent inode number of "/a" should be changed to DIR_B_INO, but f2fs didn't do that. Ref. f2fs_set_link(). In order to fix this clearly, I added i_pino in f2fs_inode_info, and whenever it needs to be changed like in f2fs_add_link() and f2fs_set_link(), it is updated temporarily in f2fs_inode_info. And later, f2fs_write_inode() stores the latest information to the inode pages. For power-off-recovery, f2fs_sync_file() triggers simply f2fs_write_inode().

Do cleanup more for better code readability. - Change the parameter set of f2fs_bio_alloc() This function should allocate a bio only since it is not something like f2fs_bio_init(). Instead, the caller should initialize the allocated bio. - Introduce SECTOR_FROM_BLOCK This macro translates a block address to its sector address.

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: NJaegeuk Kim <jaegeuk.kim@samsung.com>

This adds the following major in-memory structures in f2fs. - f2fs_sb_info: contains f2fs-specific information, two special inode pointers for node and meta address spaces, and orphan inode management. - f2fs_inode_info: contains vfs_inode and other fs-specific information. - f2fs_nm_info: contains node manager information such as NAT entry cache, free nid list, and NAT page management. - f2fs_node_info: represents a node as node id, inode number, block address, and its version. - f2fs_sm_info: contains segment manager information such as SIT entry cache, free segment map, current active logs, dirty segment management, and segment utilization. The specific structures are sit_info, free_segmap_info, dirty_seglist_info, curseg_info. In addition, add F2FS_SUPER_MAGIC in magic.h.
