cache_content_emergency_flush: Flushes the content of a file in the local cache to the FSAL data.

Flushes the content of a file in the local cache to the FSAL data. This routine should be called only from the cache_inode layer.

No lock management is done in this layer: the related pentry in the cache inode layer is locked and will prevent from concurent accesses.

Parameters:

cachedir	[IN] cachedir the filesystem where the cache resides
flushhow	[IN] should we delete local files or not ?
lw_mark_trig	[IN] shpuld we purge until low water mark is reached ?
grace_period	[IN] grace_period The grace period for a file before being considered for deletion
p_nb_flushed	[INOUT] current flushed count
p_nb_errors	[INOUT] current flush errors
p_nb_orphans	[INOUT] current orphan files detected
pcontext	[INOUT] pcontext the FSAL context for this operation
pstatys	[OUT] the status of the operation.

Returns:

CACHE_CONTENT_SUCCESS if successful, an error otherwise.
