1) Ensure mutex_init() never fails in the case of ENOMEM by retrying forever. I don't think I've ever seen this happen but it was clear after code inspection that if it did we would immediately crash. 2) Enable full debugging in check.sh for sanity tests. Might as well get as much debug as we can in the case of a failure. 3) Reworked list of kmem caches tracked by SPL in to a hash with the key based on the address of the kmem_cache_t. This should speed up the constructor/destructor/shrinker lookup needed now for newer kernel which removed the destructor support. 4) Updated kmem_cache_create to handle the case where CONFIG_SLUB is defined. The slub would occasionally merge slab caches which resulted in non-unique keys for our hash lookup in 3). To fix this we detect if the slub is enabled and then set the needed flag to prevent this merging from ever occuring. 5) New kernels removed the proc_dir_entry pointer from items registered by sysctl. This means we can no long be sneaky and manually insert things in to the sysctl tree simply by walking the proc tree. So I'm forced to create a seperate tree for all the things I can't easily support via sysctl interface. I don't like it but it will do for now. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@124 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c |
