4671a0266
Commit
4671a0266 change the parameter of the second parameter of
cfs_precpt_alloc() from a sizeof type to sizeof type *pointer.
This was incorrect in this case and it caused a crash when the LNet
layer was brought up in my testing. The reason is cfs_precpt_alloc()
creates an array of items where the arrays size is equal to the
number of CPTs that exist. Changing to type *pointer only had
cfs_precpt_alloc() create an array of pointers instead of an array
of actual data structures. This patch reverse this change and adds
comments to explain what cfs_precpt_alloc() is actually doing to
avoid potential issues like this again.
Changelog:
v1) Simple revert of the original patch
v2) Added in comments to explain why cfs_precpt_alloc() has the
arguments it uses.
