[git pull] Dealing with icache races around mkdir and object creation in general

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

 



* NFS mkdir/open_by_handle race fix
* analogous solution for FUSE, replacing the one currently in mainline
* new primitive to be used when discarding halfway set up inodes on failed
  object creation; gives sane warranties re icache lookups not returning
  such doomed by still not freed inodes.  A bunch of filesystems switched
  to that animal.
* Miklos' fix for last cycle regression in iget5_locked(); -stable will need
  a slightly different variant, unfortunately.
* misc bits and pieces around things icache-related (in adfs and jfs).
