Subject: [STACK] >3k call path in ncpfs
Date: Wed, 9 Jun 2004 14:20:02 +0200 [thread overview]
Message-ID: <20040609122002.GD21168@wohnheim.fh-wedel.de> (raw)
ncpfs has a few stack-hungry functions. Could you try to put
ncp_ioctl() and/or ncp_conn_logged_in() on a diet? Example call path
is below.
stackframes for call path too long (3004):
size function
720 ncp_ioctl
616 ncp_conn_logged_in
24 ncp_lookup_volume
0 ncp_request2
164 sock_sendmsg
0 wait_on_sync_kiocb
84 schedule
16 __put_task_struct
20 audit_free
36 audit_log_start
16 __kmalloc
0 __get_free_pages
28 __alloc_pages
284 try_to_free_pages
0 out_of_memory
0 mmput
16 exit_aio
0 __put_ioctx
16 do_munmap
0 split_vma
36 vma_adjust
0 fput
0 __fput
0 locks_remove_flock
12 panic
0 sys_sync
0 sync_inodes
308 sync_inodes_sb
0 do_writepages
128 mpage_writepages
4 write_boundary_block
0 ll_rw_block
28 submit_bh
0 bio_alloc
88 mempool_alloc
256 wakeup_bdflush
20 pdflush_operation
0 printk
0 preempt_schedule
84 schedule
