Unfortunately, part of that work caused both NLM (for NFS v3 exports) and kNFSD (for NFSv4.1+ exports) to no longer send lock notifications to clients This in itself is not a huge problem because most NFS clients will still poll the server in order to acquire a conflicted lock It's important for NLM and kNFSD that they do not block their kernel threads inside filesystem's file_lock implementations because that can produce deadlocks. We used to make sure of this by only trusting that posix_lock_file() can correctly handle blocking lock calls asynchronously, so the lock managers would only setup their file_lock requests for async callbacks if the filesystem did not define its own lock() file operation However, when GFS2 and OCFS2 grew the capability to correctly handle blocking lock requests asynchronously, they started signalling this behavior with EXPORT_OP_ASYNC_LOCK, and the check for also trusting posix_lock_file() was inadvertently dropped, so now most filesystems no longer produce lock notifications when exported over NFS Fix this by using an fop_flag which greatly simplifies the problem and grooms the way for future uses by both filesystems and lock managers alike - Add a sysctl to delete the dentry when a file is removed instead of making it a negative dentry Commit 681ce86235 ("vfs: Delete the associated dentry when deleting a file") introduced an unconditional deletion of the associated dentry when a file is removed. However, this led to performance regressions in specific benchmarks, such as ilebench.sum_operations/s, prompting a revert in commit 4a4be1ad3a ("Revert "vfs: Delete the associated dentry when deleting a file""). This reintroduces the concept conditionally through a sysctl - Expand the statmount() system call: * Report the filesystem subtype in a new fs_subtype field to e.g., report fuse filesystem subtypes * Report the superblock source in a new sb_source field * Add a new way to return filesystem specific mount options in an option array that returns filesystem specific mount options separated by zero bytes and unescaped. This allows caller's to retrieve filesystem specific mount options and immediately pass them to e.g., fsconfig() without having to unescape or split them * Report security (LSM) specific mount options in a separate security option array. We don't lump them together with filesystem specific mount options as security mount options are generic and most users aren't interested in them The format is the same as for the filesystem specific mount option array - Support relative paths in fsconfig()'s FSCONFIG_SET_STRING command - Optimize acl_permission_check() to avoid costly {g,u}id ownership checks if possible - Use smp_mb__after_spinlock() to avoid full smp_mb() in evict() - Add synchronous wakeup support for ep_poll_callback. Currently, epoll only uses wake_up() to wake up task. But sometimes there are epoll users which want to use the synchronous wakeup flag to give a hint to the scheduler, e.g., the Android binder driver. So add a wake_up_sync() define, and use wake_up_sync() when sync is true in ep_poll_callback() Fixes: - Fix kernel documentation for inode_insert5() and iget5_locked() - Annotate racy epoll check on file->f_ep - Make F_DUPFD_QUERY associative - Avoid filename buffer overrun in initramfs - Don't let statmount() return empty strings - Add a cond_resched() to dump_user_range() to avoid hogging the CPU - Don't query the device logical blocksize multiple times for hfsplus - Make filemap_read() check that the offset is positive or zero Cleanups: - Various typo fixes - Cleanup wbc_attach_fdatawrite_inode() - Add __releases annotation to wbc_attach_and_unlock_inode() - Add hugetlbfs tracepoints - Fix various vfs kernel doc parameters - Remove obsolete TODO comment from io_cancel() - Convert wbc_account_cgroup_owner() to take a folio - Fix comments for BANDWITH_INTERVAL and wb_domain_writeout_add() - Reorder struct posix_acl to save 8 bytes - Annotate struct posix_acl with __counted_by() - Replace one-element array with flexible array member in freevxfs - Use idiomatic atomic64_inc_return() in alloc_mnt_ns()" * tag 'vfs-6.13.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (35 commits) statmount: retrieve security mount options vfs: make evict() use smp_mb__after_spinlock instead of smp_mb statmount: add flag to retrieve unescaped options fs: add the ability for statmount() to report the sb_source writeback: wbc_attach_fdatawrite_inode out of line writeback: add a __releases annoation to wbc_attach_and_unlock_inode fs: add the ability for statmount() to report the fs_subtype fs: don't let statmount return empty strings fs:aio: Remove TODO comment suggesting hash or array usage in io_cancel() hfsplus: don't query the device logical block size multiple times freevxfs: Replace one-element array with flexible array member fs: optimize acl_permission_check() initramfs: avoid filename buffer overrun fs/writeback: convert wbc_account_cgroup_owner to take a folio acl: Annotate struct posix_acl with __counted_by() acl: Realign struct posix_acl to save 8 bytes epoll: Add synchronous wakeup support for ep_poll_callback coredump: add cond_resched() to dump_user_range mm/page-writeback.c: Fix comment of wb_domain_writeout_add() mm/page-writeback.c: Update comment for BANDWIDTH_INTERVAL ...		2024-11-18 09:35:30 -08:00
