New issue 10 by vmartirosyan: Some functions to simulate
http://code.google.com/p/kedr/issues/detail?id=10

We have found out several kernel functions that are used (at least) in JFS
and simulating faults in these functions could make KEDR Fault Simulation
better.

Here is the (still growing) list of such functions:

kmem_cache_create
kthread_create_on_node
mempool_create
mempool_alloc (Maybe no one expects this function to fail, but still...)
__dquot_alloc_space
filemap_write_and_wait_range
read_cache_page
write_one_page
submit_bio (A really dangerous function. Brings to crash at least in JFS)
d_alloc_root (This function is removed in Linux v3.4 and is replaced by
d_make_root)

submit_bio() function is used by FS driver for interact with block device.
Really, some other functions are also used for that interaction. Fault
simulation of that interaction is currently developed in ISP RAS(by Georgi
Riskov).

Sounds reasonable, especially for submit_bio() and friends.

Vahram, do you have the patches to add fault simulation support for
memory-related functions you have listed?
