Hi,
I rebased the work on top of -next and I applied a Jan's comment about __sb_start_write.
I did some basic tests and they are ok.
Open points:
- without change mnt_want_write several paths are still blocking paths;
- page_mkwrite still call blocking variant of __sb_start_write.
Any comments are welcome.
Regards.
Marco Stornelli (3):
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
