[PATCH 0/2] tty,vcs: vcs_seek fix + removing con_buf_mtx

[Jiri Olsa]

hi,

the vcs lseek method might race with VC removal and cause panic.

Also it seems the vcs is the only one using con_buf and con_buf_mtx,
which does not seem necessary any longer.

attached patches:
1/2 - lseek/VC-release race fix
2/2 - removing con_buf and con_buf_mtx

wbr,
jirka
