replace ->follow_link() with new method that could stay in RCU mode

2015-12-09T03:41:54+00:00

new method: ->get_link(); replacement of ->follow_link().  The differences
are:
	* inode and dentry are passed separately
	* might be called both in RCU and non-RCU mode;
the former is indicated by passing it a NULL dentry.
	* when called that way it isn't allowed to block
and should return ERR_PTR(-ECHILD) if it needs to be called
in non-RCU mode.

It's a flagday change - the old method is gone, all in-tree instances
converted.  Conversion isn't hard; said that, so far very few instances
do not immediately bail out when called in RCU mode.  That'll change
in the next commits.

don't put symlink bodies in pagecache into highmem

2015-12-09T03:41:36+00:00

kmap() in page_follow_link_light() needed to go - allowing to hold
an arbitrary number of kmaps for long is a great way to deadlocking
the system.

new helper (inode_nohighmem(inode)) needs to be used for pagecache
symlinks inodes; done for all in-tree cases.  page_follow_link_light()
instrumented to yell about anything missed.

coda: deal correctly with allocation failure from coda_cnode_makectl()

2012-01-10T16:13:13+00:00

lookup should fail with ENOMEM, not silently make dentry negative.
Switched to saner calling conventions, while we are at it.

Coda: add spin lock to protect accesses to struct coda_inode_info.

2010-10-25T15:02:40+00:00

We mostly need it to protect cached user permissions. The c_flags field
is advisory, reading the wrong value is harmless and in the worst case
we hit a slow path where we have to make an extra upcall to the
userspace cache manager when revalidating a dentry or inode.
