ceph: convert ceph_readpage to netfs_readpage

2021-04-27T21:52:22+00:00

Have the ceph KConfig select NETFS_SUPPORT. Add a new netfs ops structure and the operations for it. Convert ceph_readpage to use the new netfs_readpage helper. Signed-off-by: Jeff Layton Signed-off-by: Ilya Dryomov

ceph: rip out old fscache readpage handling

2021-04-27T21:52:21+00:00

With the new netfs read helper functions, we won't need a lot of this infrastructure as it handles the pagecache pages itself. Rip out the read handling for now, and much of the old infrastructure that deals in individual pages. The cookie handling is mostly unchanged, however.

libceph, rbd, ceph: convert to use the new mount API

2019-11-27T21:28:37+00:00

Convert the ceph filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. [ Numerous string handling, leak and regression fixes; rbd conversion was particularly broken and had to be redone almost from scratch. ] Signed-off-by: David Howells Signed-off-by: Jeff Layton Signed-off-by: Ilya Dryomov

ceph: improve fscache revalidation

2016-06-01T08:31:50+00:00

There are several issues in fscache revalidation code. - In ceph_revalidate_work(), fscache_invalidate() is called when fscache_check_consistency() return 0. This is complete wrong because 0 means cache is valid. - Handle_cap_grant() calls ceph_queue_revalidate() if client already has CAP_FILE_CACHE. This code is confusing. Client should revalidate the cache each time it got CAP_FILE_CACHE anew. - In Handle_cap_grant(), fscache_invalidate() is called if MDS revokes CAP_FILE_CACHE. This is inconsistency with the case that inode get evicted. In the later case, the cache is not discarded. Client may use the cache when inode is reloaded. This patch moves the fscache revalidation into ceph_get_caps(). Client revalidates the cache after it gets CAP_FILE_CACHE. i_rdcache_gen should keep constance while CAP_FILE_CACHE is used. If i_fscache_gen is not equal to i_rdcache_gen, client needs to check cache's consistency. Signed-off-by: Yan, Zheng

ceph: disable fscache when inode is opened for write

2016-06-01T08:31:07+00:00

All other filesystems do not add dirty pages to fscache. They all disable fscache when inode is opened for write. Only ceph adds dirty pages to fscache, but the code is buggy. Signed-off-by: Yan, Zheng

ceph: trivial buildbot warnings fix

2013-09-06T16:50:12+00:00

The linux-next build bot found a three of warnings, this addresses all of them. * non-ANSI function declaration of function 'ceph_fscache_register' and 'ceph_fscache_unregister' * symbol 'ceph_cache_netfs' was not declared, now it's extern in the header. * warning: "pr_fmt" redefined Signed-off-by: Milosz Tanski
