i_callback is an common function names for this usage, see:

reiserfs/super.c
653:static void reiserfs_i_callback(struct rcu_head *head)
661:    call_rcu(&inode->i_rcu, reiserfs_i_callback);

romfs/super.c
384:static void romfs_i_callback(struct rcu_head *head)
393:    call_rcu(&inode->i_rcu, romfs_i_callback);

hfsplus/super.c
631:static void hfsplus_i_callback(struct rcu_head *head)
640:    call_rcu(&inode->i_rcu, hfsplus_i_callback);

qnx4/inode.c
345:static void qnx4_i_callback(struct rcu_head *head)
353:    call_rcu(&inode->i_rcu, qnx4_i_callback);

gfs2/super.c
1740:static void gfs2_i_callback(struct rcu_head *head)
1748:   call_rcu(&inode->i_rcu, gfs2_i_callback);

minix/inode.c
71:static void minix_i_callback(struct rcu_head *head)
79:     call_rcu(&inode->i_rcu, minix_i_callback);

jfs/super.c
127:static void jfs_i_callback(struct rcu_head *head)
147:    call_rcu(&inode->i_rcu, jfs_i_callback);

udf/super.c
164:static void udf_i_callback(struct rcu_head *head)
172:    call_rcu(&inode->i_rcu, udf_i_callback);

ufs/super.c
1452:static void ufs_i_callback(struct rcu_head *head)
1460:   call_rcu(&inode->i_rcu, ufs_i_callback);

openpromfs/inode.c
339:static void openprom_i_callback(struct rcu_head *head)
347:    call_rcu(&inode->i_rcu, openprom_i_callback);

ubifs/super.c
275:static void ubifs_i_callback(struct rcu_head *head)
287:    call_rcu(&inode->i_rcu, ubifs_i_callback);

Therefore fs guy should know what it does by the name convension :)

Anyway, I think this patch is useful with some modification *thumb*

Thanks,
Gao Xiang
