Question

How does Linux operating system handle deadlock?

Answer 1

`Hey,

Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.

Deadlock does happen occasionally in Linux, but the kernel helps prevent most occurrences by determining if mutually exclusive locks exist. For example, if process X will have to wait for lock process Y holds and when Y is will have to wait for a lock the process X holds.

If the OS does not allow for the preemption of resource allocation and the competing processes or threads enter a circular wait condition, then a deadlock will occur.

Depending on the skill of the developer and the type of work being done on a system, deadlock can be avoided by building checks into the code. linux helps prevent deadlock by preempting resources or by putting its head in the sand and pretending there's no problem.

Kindly revert for any queries

Thanks.
