in output of lsmod command, used by column not have name of kernel modules used module. example, consider following part-output of lsmod command: module size used xen_blkfront 16512 4 ext3 137007 1 jbd 54383 1 ext3 mbcache 7438 1 ext3 in above output, ext3 module used 1 module, name not there. similarly, xen_blkfront module used 4 modules, there no names modules. but, jdb , mbcache modules used ext3 module. so, there way these missing module names ? i need because kernel not allow me rmmod ext3 module saying "error: module ext3 in use". the "used by" column shows not number of referencing modules, numer of times any kernel code has taken reference module. for file systems , device drivers, typically happens when file/device opened. the source of references not tracked.

i trying make ajax call basic authentication on hybrid mobile ios application. ajax call returns nothing hangs no success nor failure. same ajax call fires android. while checking outgoing request wireshark found authentication header missing , 401 returning server , on subsequent call authentication header send along request returns 301. but works android the same api working fine dev server in ios fails in prod server any suggestions appreciated i'm using cordova 4.2.0. i have observed in case of 401 response "www-authenticate: basic" header, ios/uiwebview seems swallow response instead of passing application layer, gives effect of service never responding. perhaps prevent authentication popups. in event behavior unexpected! edit: found cordova bug report problem: https://issues.apache.org/jira/browse/cb-2415
