Subject: [GIT PULL] vfs fixes
Hey Linus,
This includes a fix for a priority inversion in eventpoll. I did
consider it a fix and it is a single commit but it is a bit more code
than we would usually let through after -rc2. If you want me to delay
that until the merge window that's perfectly fine. You can either just
revert right after merging this or I can send you a new pull request
tomorrow.
/* Summary */
This contains another round of fixes for this cycle:
- Fix a regression caused by the anonymous inode rework. Making them
regular files causes various places in the kernel to tip over starting
with io_uring. Revert to the former status quo and port our assertion
to be based on checking the inode so we don't lose the valuable
VFS_*_ON_*() assertions that have already helped discover weird
behavior our outright bugs.
- Fix the the upper bound calculation in fuse_fill_write_pages().
- Fix priority inversion issues in the eventpoll code.
- Make secretmen use anon_inode_make_secure_inode() to avoid bypassing
the LSM layer.
- Fix a netfs hang due to missing case in final DIO read result
collection.
- Fix a double put of the netfs_io_request struct.
- Provide some helpers to abstract out NETFS_RREQ_IN_PROGRESS flag
wrangling.
- Fix infinite looping in netfs_wait_for_pause/request().
- Fix a netfs ref leak on an extra subrequest inserted into a request's
list of subreqs.
- Fix various cifs RPC callbacks to set NETFS_SREQ_NEED_RETRY if a
subrequest fails retriably.
- Fix a cifs warning in the workqueue code when reconnecting a channel.
- Fix the updating of i_size in netfs to avoid a race between testing if
we should have extended the file with a DIO write and changing i_size.
- Merge the places in netfs that update i_size on write.
- Fix coredump socket selftests.
