And the last one is xfs_mapping_buftarg(). I am completely at a loss.
As far as I can tell, inode allocated, partially initiated and -
leaked. Am I missing something?
STATIC int
xfs_mapping_buftarg(
xfs_buftarg_t *btp,
struct block_device *bdev)
{
struct backing_dev_info *bdi;
struct inode *inode;
struct address_space *mapping;
static const struct address_space_operations mapping_aops = {
.sync_page = block_sync_page,
.migratepage = fail_migrate_page,
};
inode = new_inode(bdev->bd_inode->i_sb);
if (!inode) {
printk(KERN_WARNING
"XFS: Cannot allocate mapping inode for device %s\n",
XFS_BUFTARG_NAME(btp));
return ENOMEM;
}
inode->i_mode = S_IFBLK;
inode->i_bdev = bdev;
inode->i_rdev = bdev->bd_dev;
bdi = blk_get_backing_dev_info(bdev);
if (!bdi)
bdi = &default_backing_dev_info;
mapping = &inode->i_data;
mapping->a_ops = &mapping_aops;
mapping->backing_dev_info = bdi;
mapping_set_gfp_mask(mapping, GFP_NOFS);
btp->bt_mapping = mapping;
return 0;
}
