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

[Marco Stornelli]

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
