One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + cou

If there is a error while doing a copy_from_user() for MSM_INFO_SET_NAME
make sure to truncate the object name so that there isn't a chance that
we'll have random data in the string.

Hi,
sample__fprintf_callchain currently did not use the already available
code to get the symbols of an inlined function if such information is
available in a dso. This patchset adds the required logic to add
appropriate lines.
As I am quite new to the code base of perf I am not sure how to test
t
Split the iteration over the callchain and the actual output of an
link in the callchain into separate functions. This allows to reuse
the output function in a follow up patch to add inline symbols to
the output.

Whenever a callchain shall be printed search for each address whether
inline information is available and add those symbols to the output
if symbol_conf.inline_name is enabled.

If there is an error queueing an iscsi command in
iscsi_queuecommand(), for example if the transport fails
to take the command in sessuin->tt->xmit_task(), then
the error path can call iscsi_complete_task() without
first aquiring the back_lock as required. This can
lead to things
