performance/io-cache: if the reconfigure option given is wrong, then unlock and return

2012-01-20T06:29:46+00:00

In io-cache reconfigure we take the lock on ioc_table_t, and then get the
options from the dict. If some value of some option given is wrong,
we are returning without unlocking, leading to the hang.

performance/write-behind: queue setattr fop with writes always.

2011-11-03T13:18:03+00:00

stat returned in setattr_cbk can be cached by the kernel. Hence it is
always necessary that we return correct stat, which implies that setattr
should not be out of order with respect to write fops.

performance/io-cache: move mem-pool initialisation to init.

2011-10-01T12:56:43+00:00

  - mem-pool is global structure which is stored in ioc-inode-table and hence
    can be initialised in init.

performance/quick-read: fix memory corruption.

2011-09-19T07:06:57+00:00

  - macro QR_STACK_UNWIND destroys the stub present in local and hence no need
    of explicitly calling call_stub_destroy on it.

performance/quick-read: Handle unwinding of frame corresponding to read fop properly, while validating cache.

2011-07-29T08:30:28+00:00

  - 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.
