the mutex that the waiters are using to synchronise, then transfer them
to the mutex's waiters list so that the wakeup is deferred until release
of the mutex. Improves the timings for CV sleep/wakeup by between 30-100%
in tests conducted locally on a UP system. There can be a penalty for MP
systems when only one thread is being awoken, but in practice I think it
won't be be an issue.
- pthread_signal: search for a thread that does not have a pending wakeup.
Threads can have a pending wakeup and still be on the waiters list if we
clash with an earlier pthread_cond_broadcast().
be used only as as a hint. Clear the pointer when releasing the mutex.
- When releasing a mutex, wake all waiters. Makes it possible to tranfer
waiters from another object to a mutex.
CPPPICFLAGS obly affect *.s sources only,
but we want -D_I18N_DYNAMIC flag for *.c source
(src/lib/libc/citrus_module.c and so on).
use CPICFLAGS instead.
this fix suggested by tsutsui-san in current-users@, thanks.
shell in the fuse_opt functions
+ add new debugging functions:
+ __fuse_debug(), which is used to set and retrieve the
debugging level, so that debugging information can be turned
on and off from the user-level filesystem, and
+ __fuse_pargs(), which prints out an argv vector
+ put the comment about pu_privdata back with the code it references
+ put the code to place the refuse name back into the fuse_new()
function - we have access to all the arguments there.
+ specifically include <fuse_opt.h> in <fuse.h> - this would seem to
be what FUSE itself does, judging by the number of fuse-based
filesystems I've patched to include <fuse_opt.h> specifically
+ do away with the forward reference to struct fuse_args in fuse.h,
since it is defined just after the forward reference without being
referenced in between
+ fill in the missing refuse_opt args functionality - add an arg to the
args structure in fuse_opt_add_arg() and fuse_opt_insert_arg(), and
free allocated memory in fuse_opt_free_args().
+ get rid of spurious forward declarations and prototypes.
+ if REFUSE_INHERIT_FS_CHARACTERISTICS is defined when refuse is built,
file systems inherit the vfs characteristics of their mountpoints. The
default value is NOT to inherit the vfs characteristics.
+ perform a deep copy of the fuse_args structure in fuse_mount() -
this is so that existing FUSE filesystems still DTRT when arguments
are zeroed out.
