Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/driver, fs/aio, fs/nfs, crypto/, and boards/.
Please note: The modified file under fs/nfs generates several " Mixed case identifier found" errors. Please ignore these. These cannot be fixed without changes to numerous other files. They also follow a non-standard convention that is used many files: Using lower case structure names in custom SIZEOF_ definitions.
so netdb could reuse these global variable directly

Namely these defconfig files:
boards/sim/sim/sim/configs/mtdpart/defconfig
boards/sim/sim/sim/configs/mtdrwb/defconfig
boards/sim/sim/sim/configs/rpproxy/defconfig
boards/sim/sim/sim/configs/rpserver/defconfig
boards/sim/sim/sim/configs/tcpblaster/defconfig
Because the recent versions of macOS is 64-bit only and thus
incompatible with CONFIG_SIM_M32=y.
The following defconfig files are left intact as these configs
are important for them:
boards/sim/sim/sim/configs/loadable/defconfig
boards/sim/sim/sim/configs/module32/defconfig
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under fs/inode. Utility functions under fs/incode were modified so the changes do extend to other fs/ sub-directories as well.

This commit is only for those files under fs/tmpfs and fs/spiffs. Still do do: The rest of fs/ and all of drivers/ and arch/.
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for those files under graphics/, mm/, net/, sched/, wireless/bluetooth.
Still to do: Files under fs/, drivers/, and arch. The last is 116 files and will take some effort.
nxsem_timedwait_uninterruptible() must return -ECANCELED if the thread is canceled:
include/nuttx/semaphore.h: Return if nxsem_wait() returns ECANCELED meaning that the thread waiting for the semaphore has been canceled.
sched/semaphore/sem_timedwait.c: Same change (the inline version is in semaphore.h, the non-inlined version is in sem_tickwait.c).
drivers/sensors/lps25h.c and drivers/wireless/bluetooth/bt_uart_bcm4343x.c: Make sure that the caller deals correctly with the -ECANCELED return value.
Refer to issue 619.
Because:
* A raw binary doesn't make sense for sim, where ./nuttx is
a host OS executable.
* It breaks test builds on macOS, where native objcopy
is not available.
On modern environments, bss is not executable.
Alternatively we can use the ARCH_HAVE_MODULE_TEXT mechanism.
But it's considered overkill for the sim, which is mainly
for development.
In some cases, a separate toolchain is necessary to
build modules.
E.g. the sim on macOS, where the native format is Mach-O.
By default, just use CC/LD, which is appropriate for
the most of platforms.
* The appropriate size of stack varies among archs.
E.g. for 64-bit sim, 2048 is way too small, especially when the task
happens to use host OS functionalities.
I plan to allow an arch provide its own default.
* I plan to use this to replace hardcoded "STACKSIZE = 2048" in APPDIR.
Move the prototype for the internal OS from from sched/sched/sched.h to include/nuttx/sched.h. This was done because binfmt/binfmt/excecmodule.c requires the prototype for sched_releasetcb() and was illegally including sched/sched/sched.h. That is a blatant violation of the OS modular design and the person that did this should be hung up by their thumbs. Oh... I did that back in a bad moment in 2014. Now that is made right.
This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
