I just successfully compiled and installed my kernel and then tried "make tags" command while being inside ~/git/kernels/staging directory: $ make tags make: getcwd: No such file or directory make: *** No rule to make target 'tags'. Stop. $ cd; cd - bash: cd: /home/dileep/git/kernels/staging: No such file or directory $ cd git/kernels/staging bash: cd: git/kernels/staging: No such file or directory Now there is no any "staging" directory inside ~/git/kernels. Have I lost my 1 GB of kernel source code? Please help. ‌
