The patch titled softmac: fix unbalanced mutex_lock/unlock in ieee80211softmac_wx_set_mlme has been removed from the -mm tree. Its filename was softmac-fix-unbalanced-mutex_lock-unlock-in-ieee80211softmac_wx_set_mlme.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: softmac: fix unbalanced mutex_lock/unlock in ieee80211softmac_wx_set_mlme From: Maxime Austruy <maxime@xxxxxxxxxxxxx> Found a hang while playing with wpa_supplicant and a zd1211 usb adapter using linux 2.6.19. The problem is that ieee80211softmac_wx_set_mlme forgets to release a mutex when mlme->cmd is IW_MLME_DEAUTH. The fix below allows me to kill wpa_supplicant and to restart it without having to reboot the machine. FWIW, it seems that the problem was introduced between 2.6.19-rc2 and 2.6.19-rc3 when this function was changed to use a mutex. Signed-off-by: Maxime Austruy <maxime@xxxxxxxxxxxxx> Cc: "John W.
