Hi all,
I'm trying to remove the functions lock_super/unlock_super and to push
the lock into each single fs. Currently these fs use these functions:
ext3, ext4, fat, hpfs, exofs, sysv, ufs. At the moment I used the more
conservative approach, I created a new mutex s_lock in the private sb
info for each fs, so nothing change but a couple of notes:
1) exofs/hpfs: they use lock_super only in one function so the lock
seems completely not needed and I removed it, do you see collateral effect?
2) fat/ufs: they have already got functions to lock the fs with a mutex,
I don't know at the moment if a general review of the code can give us
the possibility to "merge" the locks.
Bugs, comments, review are welcome especially from fs maintainers. Maybe
this work can be a first cleaning, after that each fs can adjust its
lock policy.
The patch is against 3.6-rc1.
