performance/write-behind: fix memory corruption

2016-01-14T05:42:13+00:00

1. while handling short writes, __wb_fulfill_short_write would've freed
   current request before moving on to next in the list if request is not
   big enough to accomodate completed number of bytes. So, make sure to
   save next member before invoking __wb_fulfill_short_write on current
   request. Also handle the case where request is exactly the size of
   remaining completed number of bytes.

2. When write request is unwound because there is a conflicting failed
   liability, make sure its deleted from tempted list. Otherwise there
   will be two unwinds (one as part handling a failed request in
   wb_do_winds and another in wb_do_unwinds).

performance/write-behind: maintain correct transit size in case of

2016-01-07T05:59:52+00:00

short writes.

1. Imagine a write when cache is filled with failed syncs.
2. This write won't be unwound since cache size has exceeded
configured limit.
3. With trickling-writes on by default, the last write request wont be
considered for winding when there is non zero in-transit size.
4. There was a bug in accounting of in-transit size when winds
resulted in short writes. Due to this bug, in-transit size used to be
non-zero even when there are no syncs in progress.
5. Due to 3 and 4, current write request won't be wound till there is
another write or fsync or flush from application. But application
can't do any other fop till current write request is unwound. This
resulted in deadlock and hence application would be hung in 'D'
state.

This patch fixes bug in accounting of in-transit size during short
writes.

wb: remove inline keyword

When compiled with -Werror flag gcc throws the following
error:

‘iov_length’ is static but used in inline
function ‘__wb_modify_write_request’ which is not static.
Let gcc decide what functions to inline and remove the inline
keyword.

build: export minimum symbols from xlators for correct resolution

2015-12-22T17:15:01+00:00

Revisiting http://review.gluster.org/#/c/11814/, which unintentionally
introduced warnings from libtool about the xlator .so names.

According to [1], the -module option must appear in the Makefile.am
file(s); if -module is defined in a macro, e.g. in configure(.ac),
then libtool will not recognize that this is a module and will emit a
warning.
