99  * edac_mc_alloc() - Allocate and partially fill a struct &mem_ctl_info.
107  * Everything is kmalloc'ed as one big chunk - more efficient.
108  * Only can be used if all structures have the same lifetime - otherwise
115  *   drivers handle multi-rank memories in different ways: in some
116  *   drivers, one multi-rank memory stick is mapped as one entry, while, in
117  *   others, a single multi-rank memory stick would be mapped into several
131  * edac_get_owner - Return the owner's mod_name of EDAC MC
139  * edac_mc_add_mc_with_groups() - Insert the @mci structure into the mci
143  * @groups: optional attribute groups for the driver-specific sysfs entries
153  * edac_mc_free() -  Frees a previously allocated @mci structure
160  * edac_has_mcs() - Check if any MCs have been allocated.
169  * edac_mc_find() - Search for a mem_ctl_info structure whose index is @idx.
179  * find_mci_by_dev() - Scan list of controllers looking for the one that
180  *	manages the @dev device.
182  * @dev: pointer to a struct device related with the MCI
187 extern struct mem_ctl_info *find_mci_by_dev(struct device *dev);
190  * edac_mc_del_mc() - Remove sysfs entries for mci structure associated with
193  * @dev: Pointer to struct &device representing mci structure to remove.
195  * Returns: pointer to removed mci structure, or %NULL if device not found.

200  * edac_mc_find_csrow_by_page() - Ancillary routine to identify what csrow
206  * Returns: on success, returns the csrow. -1 if not found.
212  * edac_raw_mc_handle_error() - Reports a memory event to userspace without
224  * edac_mc_handle_error() - Reports a memory event to userspace.
