I want to check the existence of file lock on a file in gluster file system. So that I can see from any host that whether file lock is held by any process (remote or local) on file in gluster file system.



For Example:
I have two host: h1 and h2, both with RHEL 7.2. I have one application on host h1 which has acquired the file lock on a file in gluster file system using pthread_rwlock_wrlock API. After sometimes I poweroff host h1.



Now from h2 I am using pthread_rwlock_trywrlock to see whether any lock is held on this file or not. this retuning me EBUSY till 30 minutes of poweroff of h1(its looking as if application from h1 has still held lock on it). After around 30 minutes pthread_rwlock_trywrlock returning 0.



Is there any way I can quickly check that a file in gluster is held by any any process or not?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
