[PATCH 0/4] fsfreeze: from uninterruptible to killable

From: Marco Stornelli
Date: Fri Apr 26 2013 - 04:55:22 EST


Hi,

I re-send the patch series. The first three patches are not changed since the last review, but I add a fourth patch to manage the killable state in mnt_want_write/mnt_want_write_file. I did some tests and it seems ok to me. The hot points were do_last, kern_path_create and mq_open. At the moment the path not covered is the page_mkwrite, however it could be covered with a future patch. The work made until now is sufficient to give the user the possibility to do a "kill -9" in several cases.

Marco Stornelli (4):
fsfreeze: wait in killable state in __sb_start_write
fsfreeze: added new file_start_write_killable
fsfreeze: use sb_start_write_killable instead of sb_start_write
fsfreeze: return EINTR from mnt_want_write and mnt_want_write_file
