linux-next: manual merge of the akpm tree with Linus' tree

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

 



Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in fs/dcache.c
between commits 8aab6a27332b ("vfs: reorganize dput() memory accesses")
and 0d98439ea3c6 ("vfs: use lockred "dead" flag to mark unrecoverably
dead dentries") from Linus' tree and commit "dcache: remove dentries from
LRU before putting on dispose list" from the akpm tree.

I fixed it up (hopefully - see below) and can carry the fix as necessary
(no action is required).
