we find fd marked bad while trying to fulfill lies.
* flush was queued behind some unfulfilled write.
* A previously wound write returned an error and hence fd was marked
bad with corresponding error.
* wb_fulfill_head (invocation probably rooted in wb_flush), before
winding checks for failures of previous writes and since there was a
failure, calls wb_head_done without even winding one request in head.
* wb_head_done unrefs all the requests in list "head".
* since flush was last operation on fd (and most likely last operation
on inode itself), no one invokes wb_process_queue and flush is stuck
in request queue for eternity.

do_iot_schedule() enqueues the stub and kicks the worker thread.
The stub is eventually destroyed after it has been resumed and thus
unsafe to access after being enqueued.
Though likely difficult to reproduce in a real deployment, a crash
is reproducible by running a smallfile benchmark on a replica 2
volume on a single vm. Reorder the debug log message prior to the
do_iot_schedule() call to avoid the crash.

Use the newly introduced call_unwind_error() function from

This patch remembers inodes which have been linked through readdiprlus
and makes the resolver send lookups on them.

- re-structure members of call_stub_t with new simpler layout
- easier to inspect call_stub_t contents in gdb now
- fix a bunch of double unrefs and double frees in cbk stub
- change all STACK_UNWIND to STACK_UNWIND_STRICT and thereby fixed
a lot of bad params
- implement new API call_unwind_error() which can even be called on
fop_XXX_stub(), and not necessarily fop_XXX_cbk_stub()

Maintain a list of writes (either written behind or SYNC) which are
currently "in progress" (i.e, STACK_WIND'ed towards server) and hold
off any new STACK_WIND of write (either written behind or SYNC) which
overlaps with any of the "in progress" writes.
This is a guarantee which AFR's eager-lock depends upon (though not
strictly a write-behind requirement)

This is functionality peeled out of quick-read into a separate
translator.
Fops which modify the file (where it is required to perform the
operation on the true fd) will trigger and wait for the backend
open to succeed and use that fd.
Fops like fstat() readv() etc. will use anonymous FD (configurable)
when original fd is unopened at the backend.

allows qr to do its job even if lookup originated from fuse-resolve.c
- extend test cases to include 1 second delay and retry
- fix bug while checking condition for cached unwind
qr_readv_cached() unwinds if op_ret > 0. Therefore qr_readv()
must wind to subvol only if !(op_ret > 0) (i.e, op_ret <= 0).
- qr_readv_cached() is using uninitialized @conf pointer. Thanks
to Raghavendra Bhat for catching this!

The 'least-rate-limit' io-threads translator option enables
throttling of least priority operations. This is initially intended
as a debug/diagnostic tool for users who might experience
overloaded servers via background activity (i.e., self-heal).
least-rate-limit defines the maximum number of least priority
operations the io-threads translator will dequeue in one second.
If the specified rate limit is met, the worker threads sleep for
the minimal amount of time before the next least priority operation
becomes available (or until a new request arrives).
The requests/second metric is generic and relative to a variety of
factors involved with a background operation (server, storage,
etc.). The most recent measured rate ("cached least rate") is added
to the io-threads state dump content (kill -USR1) to serve as a
reference point to throttle background activity under particular
conditions.

Automake provides a separate variable for preprocessor flags
(*_CPPFLAGS). They are already uses in a few places, so make it
consistent and use it everywhere. Note that cflags obtained from
pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with
into AM_CPPFLAGS, for example.

CFLAGS
libtool will automatically add "-fPIC" to the compiler command line as
needed, so there is no need to specify it separately.
"-shared" is normally a linker flag and has an odd effect when used with
libtool --mode=compile, namely that it inhibits production of static
objects. For that however, using AC_DISABLE_STATIC is a lot simpler.

The "-nostartfiles" is a discouraged option and is documented to
potentially result in undesired behavior. Since I see no reason why it
should be in glusterfs, remove it.

Some -D flags are present in all files, so collect them.
This adds -D${GF_HOST_OS} to some compiler command lines,
but this should not be a problem.

Rules of causal ordering implemented:
- If request A arrives after the acknowledgement (to the app,
i.e, STACK_UNWIND) of another request B, then request B is
said to have 'caused' request A.
- (corollary) Two requests, which at any point of time, are
unacknowledged simultaneously in the system can never 'cause'
each other (wb_inode->gen is based on this)
- If request A is caused by request B, AND request A's region
has an overlap with request B's region, then then the fulfillment
of request A is guaranteed to happen after the fulfillment of B.
- FD of origin is not considered for the determination of causal
ordering.
- Append operation's region is considered the whole file.
Other cleanup:
- wb_file_t not required any more.
- wb_local_t not required any more.
- O_RDONLY fd's operations now go through the queue to make sure
writes in the requested region get fulfilled before getting
processed.
- O_SYNC fd's operations now go through the queue to make sure
previously acknowledged writes on the file (via other fds) are
fulfilled before getting processed.
- Option to not honor O_SYNC is now removed.
- Option to ignore O_DIRECT is added (useful when running a VM and the
drive appears with NCQ/TCQ or WCE=1 for the guest.)
- Option to disable_first_nbytes is removed (as the cause of the
bug which required this was diagnosed to be missing TCP_NODELAY.)
- General cleanup and better conformance to coding style and convention.

* other than dict_t only 'data_t' should be the valid export from dict.h
* added 'dict_foreach_fnmatch()' API
* changed dict_lookup() to use data_t, instead of data_pair_t

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

maintaining per-fd
path based operations like stat etc, whose results will be affected by
writes have to be ordered with writes. With request queues maintained
in inode this can be done naturally, than when they are maintained per

RCA:
In cases when self-heal is in progress, self-heal fops are starved
because of least-priority. This affects other fops with conflicting
inode, entry locks with self-heal.
Fix:
This patch provides configuring enable/disable of least-priority.
Additional changes:
Moved RCHECKSUM fop to low instead of least because it will still
affect the performance of other fops if RCHECKSUM is in LEAST
priority.
Tests:
Tested that the enabling/disabling of fops is working fine.
Tested that RCHECKSUM fop priority is assigned LOW when
least-priority is disabled.
