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 When an inode log item gets superseded, * add the latest version of IRIX that will generate logs with that item * to the version name.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__ struct xfs_buf; struct xfs_bmbt_rec_64; 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_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 */ } xfs_inode_log_item_t; #define XFS_ILOG_FDATA(w) xfs_ilog_fdata(w) static inline int xfs_ilog_fdata(int w) { return (w == XFS_DATA_FORK ?
