xfs: Check for extent overflow when adding dir entries
Directory entry addition can cause the following, 1. Data block can be added/removed. A new extent can cause extent count to increase by 1. 2. Free disk block can be added/removed. Same behaviour as described above for Data block. 3. Dabtree blocks. XFS_DA_NODE_MAXDEPTH blocks can be added. Each of these can be new extents. Hence extent count can increase by XFS_DA_NODE_MAXDEPTH. Signed-off-by: Chandan Babu R <chandanrlinux@gmail.com> Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Darrick J.
