They allow applications to specify the signal mask of a thread created with pthread_create. -* Support for automatically registering threads with the Linux rseq - system call has been added. This system call is implemented starting - from Linux 4.18. The Restartable Sequences ABI accelerates user-space - operations on per-cpu data. It allows user-space to perform updates - on per-cpu data without requiring heavy-weight atomic operations. - Automatically registering threads allows all libraries, including libc, - to make immediate use of the rseq support by using the documented ABI. - The GNU C Library manual has details on integration of Restartable - Sequences. - * The GNU C Library now provides the header file <sys/single_threaded.h> which declares the variable __libc_single_threaded. Applications are encouraged to use this variable for single-thread optimizations, |
