Management of the file content cache: read/write operations.
cache_content_rdwr.c.c : Management of the file content cache, read and write operations.

| ) |
cache_content_close: closes the local fd on the cache.
Closes the local fd on the cache.
No lock management is done in this layer: the related pentry in the cache inode layer is locked and will prevent from concurent accesses.
| pentry | [IN] entry in file content layer whose content is to be accessed. |
| pclient | [IN] ressource allocated by the client for the nfs management. [OUT] returned status. |

cache_content_open: opens the local fd on the cache.
Opens the local fd on the cache.
No lock management is done in this layer: the related pentry in the cache inode layer is locked and will prevent from concurent accesses.

cache_content_rdwr: Reads/Writes through the cache layer.
Reads/Writes through the cache layer. 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.
| pentry | [IN] entry in file content layer whose content is to be accessed. |
| read_or_write | [IN] a flag of type cache_content_io_direction_t to tell if a read or write is to be done. |
| offset | [IN] absolute position (in the FSAL file) where the IO will be done. |
| pio_size_in | [IN] requested io size |
| pio_size_out | [OUT] the size of the io that was successfully made. |
| pbuffstat | [OUT] the 'stat' of entry in the data cache after the operation |
| buffer | write:[IN] read:[OUT] the buffer for the data. |
| pclient | [IN] ressource allocated by the client for the nfs management. |
| pcontext | [IN] fsal credentials for the operation. [OUT] returned status. |
