Hi,
I want to use 'l_i_reserved2' field of ext2_inode for my purpose. I
need to initialise this field when a new inode is created. I traced
sys_create call and found that 'alloc_inode' from 'struct
super_operations' is called for new inode[correct me here]. But looks
like there is no way one can access raw inode[ext2_inode] from
alloc_inode.
Is it possible to initialise 'l_i_reserved2' in alloc_inode ? What
could be other way to do it ?
static struct inode *ext2_alloc_inode(struct super_block *sb)
{
struct ext2_inode_info *ei;
ei = (struct ext2_inode_info *)kmem_cache_alloc(ext2_inode_cachep, GFP_KERNEL);
if (!ei)
return NULL;
#ifdef CONFIG_EXT2_FS_POSIX_ACL
ei->i_acl = EXT2_ACL_NOT_CACHED;
ei->i_default_acl = EXT2_ACL_NOT_CACHED;
#endif
ei->vfs_inode.i_version = 1;
}

Thanks.
