* ipw2x00: remove the right /proc/net entryLinus Torvalds2010-11-051-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 27ae60f8f7aa ("ipw2x00: replace "ieee80211" with "libipw" where appropriate") changed DRV_NAME to be "libipw", but didn't properly fix up the places where it was used to specify the name for the /proc/net/ directory. For backwards compatibility reasons, that directory name remained "ieee80211", but due to the DRV_NAME change, the error case printouts and the cleanup functions now used "libipw" instead. Which made it all fail badly. For example, on module unload as reported by Randy: WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e() name 'libipw' because it's trying to unregister a /proc directory that obviously doesn't even exist. Clean it all up to use DRV_PROCNAME for the actual /proc directory name. Reported-and-tested-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Pavel Roskin <proski@gnu.org> Cc: John W.

| * ipw2x00: replace "ieee80211" with "libipw" where appropriatePavel Roskin2010-03-151-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "ieee80211" was the old name of the common library for ipw2100 and ipw2200. It was renamed to "libipw", but some occurrences of the old name remained. Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to free_libipw(). Adjust comments and label names. Change prefixes in diagnostic messages. Keep /proc/net/ieee80211 under the original name to avoid breaking user interface. Move the affected EXPORT_SYMBOL macros to their proper places.

* | libipw: split ieee->networks into small piecesZhu Yi2010-03-101-20/+17
|/ | | | | | | | | | | | | The ieee->networks consists of 128 struct libipw_network entries. If we allocate this chunk of memory altogether, it ends up with an order 4 page allocation. High order page allocation is likely to fail on system high load. This patch splits the big chunk memory allocation into small pieces, each is 344 bytes, allocates them with 128 times.

| | | | | | | | | | | For non-monitor interfaces, the syntax for alloc_ieee80211/free_80211 is wrong. Because alloc_ieee80211 only creates (wiphy_new) a wiphy, but free_80211() does wiphy_unregister() also. This is only correct when the later wiphy_register() is called successfully, which apparently is not the case for your fw doesn't exist one.
