Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

There is no room for new vm_flags without requiring a 64-bit host
architecture. Also, the flags that are being proposed as additions for
new mmap behavior, like MAP_SYNC and MAP_DIRECT, only have relevance to
a filesystem, the core mm can mostly ignore them. So, we arrange for the
mmap(2) flags to be passed all the way through to ->mmap() so the leaf
implementation can handle them.

This conversion was performed by the following semantic patch, as well
as manual edits to handle the non-local / shared mmap handlers
(drm_gem_mmap, radeon_mmap, vmw_mmap, nfs_file_mmap, generic_file_mmap,
generic_file_readonly_mmap, ast_mmap, mgag200_mmap), and the oddity that
is proc_reg_mmap.

// mmap_flags.cocci: add an 'flags' argument to 'mmap' in 'struct file_operations'
// usage: make coccicheck COCCI=mmap_flags.cocci MODE=patch
