Revision f2ebf8ffe7af10bff02d34addbebd9199de65ed2 authored by Riccardo Mancini on 15 July 2021, 16:07:21 UTC, committed by Arnaldo Carvalho de Melo on 15 July 2021, 20:34:39 UTC 
perf trace: Free syscall->arg_fmt
 
ASan reports several memory leaks running:

  # perf test "88: Check open filename arg using perf trace + vfs_getname"

The second of these leaks is caused by the arg_fmt field of syscall not
being deallocated.

This patch adds a new function syscall__exit which is called on all
syscalls.table entries in trace__exit, which will free the arg_fmt
field.

The Linux kernel user's and administrator's guide
=================================================

The following is a collection of user-oriented documents that have been
added to the kernel over time.  There is, as yet, little overall order or
organization here — this material was not written to be a single, coherent
document!  With luck things will improve quickly over time.

This initial section contains overall information, including the README
file describing the kernel as a whole, documentation on kernel parameters,
etc.

Here is a set of documents aimed at users who are trying to track down
problems and bugs in particular.
