- Hard-code the inodes for eventfs to the same number for files, and the same number for directories. - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZak5GxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvZYAP0ZO4YN9fKnl6Cw1GNCwPtMO13dEg9D mIvwftxX8DuaegD/fQFY9gBc+ZMSCbiWVJBAyfO57NPvHk4S3slwPVuL9gA= =iKJI -----END PGP SIGNATURE----- Merge tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull eventfs updates from Steven Rostedt: - Remove "lookup" parameter of create_dir_dentry() and create_file_dentry(). These functions were called by lookup and the readdir logic, where readdir needed it to up the ref count of the dentry but the lookup did not. A "lookup" parameter was passed in to tell it what to do, but this complicated the code. It is better to just always up the ref count and require the caller to decrement it, even for lookup. - Modify the .iterate_shared callback to not use the dcache_readdir() logic and just handle what gets displayed by that one function. This removes the need for eventfs to hijack the file->private_data from the dcache_readdir() "cursor" pointer, and makes the code a bit more sane - Use the root and instance inodes for default ownership. Instead of walking the dentry tree and updating each dentry gid, use the getattr(), setattr() and permission() callbacks to set the ownership and permissions using the root or instance as the default - Some other optimizations with the eventfs iterate_shared logic - Hard-code the inodes for eventfs to the same number for files, and the same number for directories - Have getdent() not create dentries/inodes in iterate_shared() as now it has hard-coded inode numbers - Use kcalloc() instead of kzalloc() on a list of elements - Fix seq_buf warning and make static work properly. * tag 'eventfs-v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: seq_buf: Make DECLARE_SEQ_BUF() usable eventfs: Use kcalloc() instead of kzalloc() eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Have the inodes all for files and directories all be the same eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Stop using dcache_readdir() for getdents() eventfs: Remove "lookup" parameter from create_dir/file_dentry() |
