In case sav->sav_config was NULL the body of the function would skip the iteration of the l2 cache devices and will just cleanup the old devices. However, this wasn't very obvious since the null check was performed after the loop body and after the old devices were cleaned. Refactor the code so that it's now obvious when the iteration of the l2cache devices is skipped. This fixes the following cppcheck warning: [module/zfs/spa.c:1552]: (error) Possible null pointer dereference: newvdevs Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Nikolay Borisov <n.borisov.lkml@gmail.com> Closes #5087 |
