Byte Range lock performance fixes for cifs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Has anyone reviewed Pavel's recent patch series on byte range locks? I
have reviewed and merged his earlier lock related ones, but have not
finished looking at these.  They are an interesting series.  In the
future these will be even more useful (with cifs we often have oplock,
but with smb2.1, the addition of leases, means that we are more likely
to have caching privilege for a file than in the past since it can
handle upgrades of leases and reacquiring leases)

CIFS: Make cifs_push_locks send as many locks at once...
CIFS: Send as many mandatory unlock ranges at once...
CIFS: Implement caching mechanism for posix brlocks
CIFS: Implement caching mechanism for mandatory brlocks

They were posted on the linux-cifs list but are also at:
