Name:__test_and_set_bit - Set a bit and return its old value*@nr: Bit to set*@addr: Address to count from* This operation is non-atomic. If two instances of this operation race, one* can appear to succeed but actually fail.
Proto:static inline bool __test_and_set_bit(long nr, volatile unsigned long *addr)
Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| long | nr | |
| volatile unsigned long * | addr |
| 71 | kasan_check_write(addr + BIT_WORD(nr), sizeof(long)) |
| 72 | Return arch___test_and_set_bit(nr, addr) |
| Name | Describe |
|---|---|
| node_set_mark | rns true if the bit was set |
| kasan_bitops | |
| do_clear_cpu_cap | |
| warn_on_bintable | Print each legacy sysctl (approximately) only once.* To avoid making the tables non-const use a external* hash-table instead.* Worst case hash collision: 6, but very rarely.* NOTE! We don't use the SMP-safe bit tests. We simply* don't care enough. |
| vm_lock_anon_vma | |
| keyctl_pkey_params_parse | Parse the information string which consists of key=val pairs. |
