2022-01-12dt-bindings: net: mdio: Drop resets/reset-names child propertiesRob Herring
resets/reset-names are device specific and don't belong in the MDIO bus schema. For example, it doesn't match what is defined for the "qca,ar9331-switch" binding which defines "reset-names" to be "switch" rather than "phy". Neither name is that useful IMO. Other child properties are also device specific, but those won't conflict with device schemas.

2022-01-12x86/entry_32: Fix segment exceptionsPeter Zijlstra
The LKP robot reported that commit in Fixes: caused a failure. Turns out the ldt_gdt_32 selftest turns into an infinite loop trying to clear the segment. As discovered by Sean, what happens is that PARANOID_EXIT_TO_KERNEL_MODE in the handle_exception_return path overwrites the entry stack data with the task stack data, restoring the "bad" segment value. Instead of having the exception retry the instruction, have it emulate the full instruction. Replace EX_TYPE_POP_ZERO with EX_TYPE_POP_REG which will do the equivalent of: POP %reg; MOV $imm, %reg. In order to encode the segment registers, add them as registers 8-11 for 32-bit. By setting regs->[defg]s the (nested) RESTORE_REGS will pop this value at the end of the exception handler and by increasing regs->sp, it will have skipped the stack slot. This was debugged by Sean Christopherson <seanjc@google.com>.

2022-01-119p, afs, ceph, nfs: Use current_is_kswapd() rather than ↵David Howells
gfpflags_allow_blocking() In 9p, afs ceph, and nfs, gfpflags_allow_blocking() (which wraps a test for __GFP_DIRECT_RECLAIM being set) is used to determine if ->releasepage() should wait for the completion of a DIO write to fscache with something like: if (folio_test_fscache(folio)) { if (!gfpflags_allow_blocking(gfp) || !(gfp & __GFP_FS)) return false; folio_wait_fscache(folio); } Instead, current_is_kswapd() should be used instead. Note that this is based on a patch originally by Zhaoyang Huang[1]. In addition to extending it to the other network filesystems and putting it on top of my fscache rewrite, it also needs to include linux/swap.h in a bunch of places.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull fs idmapping updates from Christian Brauner: "This contains the work to enable the idmapping infrastructure to support idmapped mounts of filesystems mounted with an idmapping. In addition this contains various cleanups that avoid repeated open-coding of the same functionality and simplify the code in quite a few places. We also finish the renaming of the mapping helpers we started a few kernel releases back and move them to a dedicated header to not continue polluting the fs header needlessly with low-level idmapping helpers. With this series the fs header only contains idmapping helpers that interact with fs objects. Currently we only support idmapped mounts for filesystems mounted without an idmapping themselves. This was a conscious decision mentioned in multiple places (cf. [1]). As explained at length in [3] it is perfectly fine to extend support for idmapped mounts to filesystem's mounted with an idmapping should the need arise. The need has been there for some time now (cf. [2]). Before we can port any filesystem that is mountable with an idmapping to support idmapped mounts in the coming cycles, we need to first extend the mapping helpers to account for the filesystem's idmapping. This again, is explained at length in our documentation at [3] and also in the individual commit messages so here's an overview. Currently, the low-level mapping helpers implement the remapping algorithms described in [3] in a simplified manner as we could rely on the fact that all filesystems supporting idmapped mounts are mounted without an idmapping. In contrast, filesystems mounted with an idmapping are very likely to not use an identity mapping and will instead use a non-identity mapping. So the translation step from or into the filesystem's idmapping in the remapping algorithm cannot be skipped for such filesystems. Non-idmapped filesystems and filesystems not supporting idmapped mounts are unaffected by this change as the remapping algorithms can take the same shortcut as before. If the low-level helpers detect that they are dealing with an idmapped mount but the underlying filesystem is mounted without an idmapping we can rely on the previous shortcut and can continue to skip the translation step from or into the filesystem's idmapping. And of course, if the low-level helpers detect that they are not dealing with an idmapped mount they can simply return the relevant id unchanged; no remapping needs to be performed at all. These checks guarantee that only the minimal amount of work is performed. As before, if idmapped mounts aren't used the low-level helpers are idempotent and no work is performed at all" Link: 2ca4dcc4909d ("fs/mount_setattr: tighten permission checks") [1] Link: https://github.com/containers/podman/issues/10374 [2] Link: Documentations/filesystems/idmappings.rst [3] Link: a65e58e791a1 ("fs: document and rename fsid helpers") [4] * tag 'fs.idmapped.v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: support mapped mounts of mapped filesystems fs: add i_user_ns() helper fs: port higher-level mapping helpers fs: remove unused low-level mapping helpers fs: use low-level mapping helpers docs: update mapping documentation fs: account for filesystem mappings fs: tweak fsuidgid_has_mapping() fs: move mapping helpers fs: add is_idmapped_mnt() helper

2022-01-11ceph: add fscache writeback supportJeff Layton
When updating the backing store from the pagecache (a'la writepage or writepages), write to the cache first. This allows us to keep caching files even when they are being written, as long as we have appropriate caps.

2022-01-11ceph: conversion to new fscache APIJeff Layton
Now that the fscache API has been reworked and simplified, change ceph over to use it. With the old API, we would only instantiate a cookie when the file was open for reads. Change it to instantiate the cookie when the inode is instantiated and call use/unuse when the file is opened/closed. Also, ensure we resize the cached data on truncates, and invalidate the cache in response to the appropriate events. This will allow us to plumb in write support later.
