Minor VFS File Optimizations Merged For Linux 6.15
Among other Linux Virtual File-System (VFS) changes submitted and already merged for Linux 6.15 was a set of minor performance optimizations around VFS file operations.
Christian Brauner summed up the VFS file optimization work by kernel developer Mateusz Guzik as: Add file_ref_put_close() to better handle the common case where closing a file descriptor also operates on the last reference and build fput_close_sync() and fput_close() on top of it. - Reduce the work done in fdget_pos() by predicting that the file was found and by explicitly comparing the reference count to one and ignoring the dead zone."
