[PATCH v2 0/7] virtiofsd: Changed various allocations to GLib functions
Posted by Mahmoud Mandour 3 years ago
Replaced allocations done using malloc(), calloc(), and realloc()
to their equivalent functions in GLib.

Memory that is allocated locally and freed when the function exits
are annotated g_autofree so that the deallocation is automatically
handled. Subsequently, I could remove a bunch of free() calls.

Also, tried to keep the semantics of the code as is, but when the
allocation is a small one, or a crucial one, I replaced the
NULL-checking mechanisms with glib's functions that crash on error.

This is related to a patch that I had submitted as a part of a
previous series. The previous patch had some errors. Also, I thought
that it's better to split the patch into smaller pieces.
