* io-cache: fix table->max_pri to 1 as the lowest priorityAnand Avati2009-09-161-1/+2
| | | | | | | | | | | | | patch http://patches.gluster.com/patch/1319/ breaks when no priority is mentioned in the config. the patch makes ioc_get_priority() return 1 as the value when no priority is given, but ioc_get_priority_list() was still returning 0 as the max_pri (maximum priority) which would result in lru list heads not getting initialized Signed-off-by: Anand V.

* 2.0.6 patch for io-cache pattern-matched non-cachingStephan von Krawczynski2009-09-151-5/+23
| | | | | | | | | | | | | | | | | | Hello all, here is a small feature patch. Its intention is to give the user more control over the files performance/io-cache really caches. If the user knows exactly which files should be cached and which shouldn't there is currently no way to tell glusterfs _not_ to cache certain pattern. This patch allows you to disable caching by setting the priority of a pattern to "0". If you do not give any priority option it works just like before and caches everything. Honestly I am not totally sure that disabling caching works the way we did it, please comment. Signed-off-by: Anand V.

* io-cache: prevent frames from getting woken up while page is getting validatedAnand Avati2009-06-031-1/+1
| | | | | | | | | | | | | | | | 1. A page will be put on the inode waitq if the 'freshness' has to be verified with an fstat() 2. while the fstat is in transit, other calls (like lookup) can update ioc_inode->tv, resetting the freshness (page still on inode waitq) 3. Another read request on the same page, after the updated freshness, will wake up the page frames neglecting the fact that the page is also waiting on the inode (waiting for the fstat completion) 4. once the page's frames are woken, the page becomes elegible for purging and can get destroyed for various reasons, leaving a destroyed page pointer in the inode's waitq 5. fstat returns and hits the destroyed page pointer causing a crash The fix is to all together disable cache hits when any page of the same inode is under validation. The otherwise cache hit will now be subjected to the ongoing validation by getting queued to the inode waitq. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
