ceph: drop usage of page_index

2024-07-04T02:29:55+00:00

page_index is needed for mixed usage of page cache and swap cache, for
pure page cache usage, the caller can just use page->index instead.

It can't be a swap cache page here, so just drop it.

ceph: get rid of passing callbacks in __dentry_leases_walk()

2024-01-15T14:54:54+00:00

__dentry_leases_walk() gets a callback and calls it for
a bunch of denties; there are exactly two callers and
we already have a flag telling them apart - lwc->dir_lease.

Seeing that indirect calls are costly these days, let's
get rid of the callback and just call the right function
directly.  Has a side benefit of saner signatures...

dentry: switch the lists of children to hlist

2023-11-25T07:32:13+00:00

Saves a pointer per struct dentry and actually makes the things less
clumsy.  Cleaned the d_walk() and dcache_readdir() a bit by use
of hlist_for_... iterators.

A couple of new helpers - d_first_child() and d_next_sibling(),
to make the expressions less awful.

ceph: pass an idmapping to mknod/symlink/mkdir

2023-11-03T22:28:34+00:00

Enable mknod/symlink/mkdir iops to handle idmapped mounts.
This is just a matter of passing down the mount's idmapping.

ceph: print cluster fsid and client global_id in all debug logs

2023-11-03T22:28:33+00:00

Multiple CephFS mounts on a host is increasingly common so
disambiguating messages like this is necessary and will make it easier
to debug issues.

At the same this will improve the debug logs to make them easier to
troubleshooting issues, such as print the ino# instead only printing
the memory addresses of the corresponding inodes and print the dentry
names instead of the corresponding memory addresses for the dentry,etc.

We need to covert the inode to ceph_client in the following commit,
