ceph: fix missing dput in ceph_set_acl

2014-01-31T16:14:06+00:00

Add matching dput() for d_find_alias().  Move d_find_alias() down a bit
at Julia's suggestion.

ceph: simplify ceph_{get,init}_acl

2014-01-31T03:26:17+00:00

 - ->get_acl only gets called after we checked for a cached ACL, so no
   need to call get_cached_acl again.
 - no need to check IS_POSIXACL in ->get_acl, without that it should
   never get set as all the callers that set it already have the check.
 - you should be able to use the full posix_acl_create in CEPH

ceph: fix posix ACL hooks

2014-01-30T00:05:28+00:00

The merge of commit 7221fe4c2ed7 ("ceph: add acl for cephfs") raced with
upstream changes in the generic POSIX ACL code (eg commit 2aeccbe957d0
"fs: add generic xattr_acl handlers" and others).

Some of the fallout was fixed in commit 4db658ea0ca ("ceph: Fix up after
semantic merge conflict"), but it was incomplete: the set_acl
inode_operation wasn't getting set, and the prototype needed to be
adjusted a bit (it doesn't take a dentry anymore).

ceph: Fix up after semantic merge conflict

2014-01-29T02:06:18+00:00

The previous ceph-client merge resulted in ceph not even building,
because there was a merge conflict that wasn't visible as an actual data
conflict: commit 7221fe4c2ed7 ("ceph: add acl for cephfs") added support
for POSIX ACL's into Ceph, but unluckily we also had the VFS tree change
a lot of the POSIX ACL helper functions to be much more helpful to
filesystems (see for example commits 2aeccbe957d0 "fs: add generic
xattr_acl handlers", 5bf3258fd2ac "fs: make posix_acl_chmod more useful"
and 37bc15392a23 "fs: make posix_acl_create more useful")

The reason this conflict wasn't obvious was many-fold: because it was a
semantic conflict rather than a data conflict, it wasn't visible in the
git merge as a conflict.  And because the VFS tree hadn't been in
linux-next, people hadn't become aware of it that way.  And because I
was at jury duty this morning, I was using my laptop and as a result not
doing constant "allmodconfig" builds.

Anyway, this fixes the build and generally removes a fair chunk of the
Ceph POSIX ACL support code, since the improved helpers seem to match
really well for Ceph too.  But I don't actually have any way to *test*
the end result, and I was really hoping for some ACK's for this.  Oh,
well.

Not compiling certainly doesn't make things easier to test, so I'm
committing this without the acks after having waited for four hours...
Plus it's what I would have done for the merge had I noticed the
semantic conflict..

ceph: cast PAGE_SIZE to size_t in ceph_sync_write()

2014-01-28T17:57:21+00:00

Use min_t(size_t, ...) instead of plain min(), which does strict type
checking, to avoid compile warning on i386.

ceph: fix dout() compile warnings in ceph_filemap_fault()

2014-01-28T17:57:06+00:00

PAGE_CACHE_SIZE is unsigned long on all architectures, however size_t
is either unsigned int or unsigned long.  Rather than change format
strings, cast PAGE_CACHE_SIZE to size_t to be in line with dout()s in
ceph_page_mkwrite().

Switch ceph_calc_ceph_pg() to new oloc and oid abstractions and rename
it to ceph_oloc_oid_to_pg() to make its purpose more clear.

ceph: add imported caps when handling cap export message

2014-01-21T08:30:31+00:00

Version 3 cap export message includes information about the imported
caps. It allows us to add the imported caps if the corresponding cap
import message still hasn't been received.

This allow us to handle situation that the importer MDS crashes and
the cap import message is missing.
