* performance/quick-read: Handle unwinding of frameRaghavendra G2011-07-291-115/+220
| | | | | | | | | | | | | | | | | corresponding to read fop properly, while validating cache. - there was a possibility of double unwind in case of errors. - use a new frame to do open in fd-based fops. In case of errors, qr_resume_pending_ops will be called to resume all the fops waiting on open. Hence if we use frame corresponding to fop (without creating a new one), there is a possibility of frame being freed by the time open would've returned to quick-read.

* quick-read: Fix dirname(3) usageAnand Avati2011-07-291-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | glibc dirname() modify the string it is given and returns it. glusterfs takes this behavior for granted, and assume that if it gives a malloc'ed string to dirname(), then it can free()) the return value. Here is what SUSv2 says: http://opengroup.org/onlinepubs/007908799/xsh/dirname.html "The dirname() function may modify the string pointed to by path, and may return a pointer to static storage" At least NetBSD returns a static storage. glusterfs will return it to a calling function that has the responsability to free it, causing a SIGSEGV.

* performance/quick-read: propagate errors during open back to actual fops.Raghavendra G2011-07-291-336/+845
| | | | | | | | | | | | | | - If open fails and there are any other fops waiting on that open, those fops should also unwind with appropriate errors. Before this patch, irrespective of success/failure of open, fops waiting on it were stack_wound and since fd was invalid, they would fail with EBADFD errors. Due to this actual error would've got masked by EBADFD.
