* core: reduce the usage of global variablesAmar Tumballi2012-08-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | * move all the 'logging' related global variables into ctx * make gf_fop_list a 'const' global array, hence no init(), no edits. * make sure ctx is allocated without any dependancy on memory-accounting infrastructure, so it can be the first one to get allocated * globals_init() should happen with ctx as argument not yet fixed below in this patchset: * anything with 'THIS' related globals * anything related to compat_errno related globals as its one time init'd and not changed later on. * statedump related globals Change-Id: Iab8fc30d4bfdbded6741d66ff1ed670fdc7b7ad2 Signed-off-by: Amar Tumballi <amarts@redhat.com> BUG: 764890 Reviewed-on: http://review.gluster.com/3767 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

* mempool: add more counters to understand the usage scenarios properlyAmar Tumballi2012-02-271-0/+3
| | | | | | | | | | | | | | current design of mempool is to fallback to standard calloc/free if all the buffers in pool are exhausted. Understanding more about those numbers will help us to tune mempool parameters properly over time.

* mem-pool: Restructure mem-pool behaviourShehjar Tikoo2009-05-191-0/+1
| | | | | | | | | | | | | | | | | | This commit changes mem-pool behaviour to return a directly usable address by performing the required adjustment on the address being returned. This is different from the previous behaviour where we're trying to fit into the requested size, the list_head*2 also. This is not efficient enough in terms of space but hopefully works better than not having any mem-pool at all. Besides, I am not comfortable with mem-pool meta-data and caller-useable memory area being the same because of the potential for mem-pool's data structure corruption.
