46 * A buffer has a format structure overhead in the log in addition
47 * to the data, so we need to take this into account when reserving
48 * space in a transaction for a buffer. Round the space required up
49 * to a multiple of 128 bytes so that we don't change the historical
50 * reservation that has been used for this overhead.
53 xfs_buf_log_overhead(void)
55 return round_up(sizeof(struct xlog_op_header) +
56 sizeof(struct xfs_buf_log_format), 128);
60 * Calculate out transaction log reservation per item in bytes.
62 * The nbufs argument is used to indicate the number of items that
63 * will be changed in a transaction. size is used to tell how many
64 * bytes should be reserved per item.
71 return nbufs * (size + xfs_buf_log_overhead());
75 * Various log reservation values.
77 * These are based on the size of the file system block because that is what
78 * most transactions manipulate. Each adds in an additional 128 bytes per
79 * item logged to try to account for the overhead of the transaction mechanism.
81 * Note: Most of the reservations underestimate the number of allocation
82 * groups into which they could free extents in the xfs_bmap_finish() call.
83 * This is because the number in the worst case is quite high and quite
84 * unusual. In order to fix this we need to change xfs_bmap_finish() to free
85 * extents in only a single AG at a time. This will require changes to the
86 * EFI code as well, however, so that the EFI for the extents not freed is
87 * logged again in each transaction. See SGI PV #261917.
89 * Reservation functions here avoid a huge stack in xfs_trans_init due to
90 * register overflow from temporaries in the calculations.
95 * In a write transaction we can allocate a maximum of 2
96 * extents. This gives:
97 * the inode getting the new extents: inode size
98 * the inode's bmap btree: max depth * block size
99 * the agfs of the ags from which the extents are allocated: 2 * sector
100 * the superblock free block counter: sector size
101 * the allocation btrees: 2 exts * 2 trees * (2 * max depth - 1) * block size
102 * And the bmap_finish transaction can free bmap blocks in a join:
103 * the agfs of the ags containing the blocks: 2 * sector size
104 * the agfls of the ags containing the blocks: 2 * sector size
105 * the super block free block counter: sector size
