The size of the inline data/extents/b-tree root to be logged - * (if any) is indicated in the ilf_dsize field. Changes to this structure - * must be added on to the end. - * - * Convention for naming inode log item versions : The current version - * is always named XFS_LI_INODE. When an inode log item gets superseded, - * add the latest version of IRIX that will generate logs with that item - * to the version name. - * - * -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first - * union (ilf_u) field. This was released with IRIX 5.3-XFS. - * -Version 2 of this structure (XFS_LI_6_1_INODE) is currently the entire - * structure. This was released with IRIX 6.0.1-XFS and IRIX 6.1. - * -Version 3 of this structure (XFS_LI_INODE) is the same as version 2 - * so a new structure definition wasn't necessary. However, we had - * to add a new type because the inode cluster size changed from 4K - * to 8K and the version number had to be rev'ved to keep older kernels - * from trying to recover logs with the 8K buffers in them. The logging - * code can handle recovery on different-sized clusters now so hopefully - * this'll be the last time we need to change the inode log item just - * for a change in the inode cluster size. This new version was - * released with IRIX 6.2. - */ -typedef struct xfs_inode_log_format { - unsigned short ilf_type; /* inode log item type */ - unsigned short ilf_size; /* size of this item */ - uint ilf_fields; /* flags for fields logged */ - ushort ilf_asize; /* size of attr d/ext/root */ - ushort ilf_dsize; /* size of data/ext/root */ - xfs_ino_t ilf_ino; /* inode number */ - union { - xfs_dev_t ilfu_rdev; /* rdev value for dev inode*/ - uuid_t ilfu_uuid; /* mount point value */ - } ilf_u; - __int64_t ilf_blkno; /* blkno of inode buffer */ - int ilf_len; /* len of inode buffer */ - int ilf_boffset; /* off of inode in buffer */ -} xfs_inode_log_format_t; - -/* Initial version shipped with IRIX 5.3-XFS */ -typedef struct xfs_inode_log_format_v1 { - unsigned short ilf_type; /* inode log item type */ - unsigned short ilf_size; /* size of this item */ - uint ilf_fields; /* flags for fields logged */ - uint ilf_dsize; /* size of data/ext/root */ - xfs_ino_t ilf_ino; /* inode number */ - union { - xfs_dev_t ilfu_rdev; /* rdev value for dev inode*/ - uuid_t ilfu_uuid; /* mount point value */ - } ilf_u; -} xfs_inode_log_format_t_v1; - -/* - * Flags for xfs_trans_log_inode flags field. - */ -#define XFS_ILOG_CORE 0x001 /* log standard inode fields */ -#define XFS_ILOG_DDATA 0x002 /* log i_df.if_data */ -#define XFS_ILOG_DEXT 0x004 /* log i_df.if_extents */ -#define XFS_ILOG_DBROOT 0x008 /* log i_df.i_broot */ -#define XFS_ILOG_DEV 0x010 /* log the dev field */ -#define XFS_ILOG_UUID 0x020 /* log the uuid field */ -#define XFS_ILOG_ADATA 0x040 /* log i_af.if_data */ -#define XFS_ILOG_AEXT 0x080 /* log i_af.if_extents */ -#define XFS_ILOG_ABROOT 0x100 /* log i_af.i_broot */ - -#define XFS_ILOG_NONCORE (XFS_ILOG_DDATA | XFS_ILOG_DEXT | \ - XFS_ILOG_DBROOT | XFS_ILOG_DEV | \ - XFS_ILOG_UUID | XFS_ILOG_ADATA | \ - XFS_ILOG_AEXT | XFS_ILOG_ABROOT) - -#define XFS_ILOG_DFORK (XFS_ILOG_DDATA | XFS_ILOG_DEXT | \ - XFS_ILOG_DBROOT) - -#define XFS_ILOG_AFORK (XFS_ILOG_ADATA | XFS_ILOG_AEXT | \ - XFS_ILOG_ABROOT) - -#define XFS_ILOG_ALL (XFS_ILOG_CORE | XFS_ILOG_DDATA | \ - XFS_ILOG_DEXT | XFS_ILOG_DBROOT | \ - XFS_ILOG_DEV | XFS_ILOG_UUID | \ - XFS_ILOG_ADATA | XFS_ILOG_AEXT | \ - XFS_ILOG_ABROOT) - -#define XFS_ILI_HOLD 0x1 -#define XFS_ILI_IOLOCKED_EXCL 0x2 -#define XFS_ILI_IOLOCKED_SHARED 0x4 - -#define XFS_ILI_IOLOCKED_ANY (XFS_ILI_IOLOCKED_EXCL | XFS_ILI_IOLOCKED_SHARED) - - -#ifdef __KERNEL__ +/* kernel only definitions */ struct xfs_buf; -struct xfs_bmbt_rec_64; +struct xfs_bmbt_rec; struct xfs_inode; struct xfs_mount; - typedef struct xfs_inode_log_item { xfs_log_item_t ili_item; /* common portion */ struct xfs_inode *ili_inode; /* inode ptr */ xfs_lsn_t ili_flush_lsn; /* lsn at last flush */ xfs_lsn_t ili_last_lsn; /* lsn at last transaction */ - unsigned short ili_ilock_recur; /* lock recursion count */ - unsigned short ili_iolock_recur; /* lock recursion count */ - unsigned short ili_flags; /* misc flags */ + unsigned short ili_lock_flags; /* lock flags */ unsigned short ili_logged; /* flushed logged data */ unsigned int ili_last_fields; /* fields when flushed */ - struct xfs_bmbt_rec_64 *ili_extents_buf; /* array of logged - data exts */ - struct xfs_bmbt_rec_64 *ili_aextents_buf; /* array of logged - attr exts */ - unsigned int ili_pushbuf_flag; /* one bit used in push_ail */ - -#ifdef DEBUG - uint64_t ili_push_owner; /* one who sets pushbuf_flag - above gets to push the buf */ -#endif -#ifdef XFS_TRANS_DEBUG - int ili_root_size; - char *ili_orig_root; -#endif - xfs_inode_log_format_t ili_format; /* logged structure */ + unsigned int ili_fields; /* fields to be logged */ } xfs_inode_log_item_t; +static inline int xfs_inode_clean(xfs_inode_t *ip) +{ + return !ip->i_itemp || !(ip->i_itemp->ili_fields & XFS_ILOG_ALL); +} -#if XFS_WANT_FUNCS || (XFS_WANT_SPACE && XFSSO_XFS_ILOG_FDATA) -int xfs_ilog_fdata(int w); -#define XFS_ILOG_FDATA(w) xfs_ilog_fdata(w) -#else -#define XFS_ILOG_FDATA(w) \ - ((w) == XFS_DATA_FORK ?
